At last

The Lexus Portal reports an update for the navigation on my GS450h Premier Gen4 (2012)! It now gives 02-16-50 as the latest version for my EMVN (11HDD) model navigation. I still have the original 2012 version (12-02-00 (2011-11-0) installed but the up to date version when I bought the car was 2015-05-1 which indicates they seem to have changed the version naming format. Establishing what the latest update is seems difficult and inclines me to wonder if the information one receives is always accurate. The garage where I bought the car claimed that they could supply me a updated data from early 2016 but the Lexus Portal has remained with the 2015-05-01 until very recently. I contacted Lexus tech staff through the Portal but they just referred me back to the garage. One wonders if the tech staff don't know who does.

I'm tempted to get this latest update since I have a deal with the garage to get it at half price because of a misunderstanding when I bought the car but £80 is still quite a chunk of cash for a piece of software which will soon be out of date on fairly clunky bit of kit (although the GS screen is great and I like the voice guidance). Google Maps on my mobile seems brilliant - I can even tell it verbally to provide the route to somewhere and it does it quite well. I also understand that Sygic is good for Android at about £17.50 - £29 depending if one wants only European maps or World coverage and either the standard system or the one with Traffic information (The maps can be downloaded and don't need an internet connection - I think the latter is only needed for Traffic).

So how can I get my mobile screen displayed on the car's screen and controlled by the car's remote touch/steering wheel? Viastech provided a system for the Gen 3 GS and I've picked up rumours about BeatSonic, MirrorLink and Grom but don't know anything about them. Has anyone experience or advice on how to do this and how well it works? I like the Lexus screen and I don't really want to have to clamp the phone to the car and have charging wires draping all over my lovey interior.

Still trying to have an update in my GS300h with same navi system, but forget to have mirroring of cell phone. In Lexus (and Toyota also) are making a mess with updates.

Lexus are refusing to support CarPlay / Android Auto for their latest cars, even though most other manufactures now provide support. Clinging on to an old business model is never a good strategy, I expect they will lose sales because of it.

Vaistech are the best systems out their but are expensive and they typically cannot guarantee they will work with UK vehicles (until at least one customer purchases and tests it).

Personally I just purchased a Brodit holder and hid the wire as best I could. I can charge my phone and have choice of infinitely better Nav applications that the built in system.

Yes Zotto I think we are caught with systems in our cars which did not have a huge production output in our countries and navigation systems that changed quite often. I can understand why we may not be Lexus' highest priority which is why I'd rather find a way of linking to a mobile phone system.

Yes, Colin. Vaistech is expensive until one compares it to updating the Lexus maps! Sadly they don't seem to make a system which will work with the navigation system in my car. Maybe I'll follow your course with a phone holder but it isn't really what I'm after. Lexus will never be able to keep up with mapping applications which can be sold cheaply/free to a vast number of consumers and which do the job better. All they get by trying to do so is adverse criticism.

Updating maps on Lexus premium navigation system with HDD is quite complicate, as it's not sufficient to buy a DVD with maps, but to avoid copying there is a code registration, and the code has to be generated from navy system number.

Maps are from Navteq.

Thanks for that Luigi. I've only scan read it but it certainly does look complex but not, I think, so complicated as to justify the Lexus pricing.

I contacted Beat-Sonic. They have a system with lots of wires, plugs and boxes which connects up behind the audio system. It mirror the Android phone on the screen but does not allow control using remote touch. I looked at a You-tube video of it working - it looks a bit clunky and at close on £300 definitely not for me.

Bringing an old post back to life I am working on using an android phone or tablet through the GS450H screen. I am going to use a ball mouse or possibly a touch pad and buttons from an old laptop to give a mouse pointer on screen. This is working on the android devices I have. This will mean the Lexus touch screen will show the mouse pointer, and the "mouse/touch pad" will be used to input instructions "post code ect" to the android devise via the touch screen mouse pointer. Voice input could also be used.

For those that like Tom Tom the software is available for android phones, and tablets in Playstore for very little money, but free software is also available.

I am at the moment working on the method of transferring the video from the android device to the Lexus screen, but I have a few ideas on how to accomplish this in the simplest manner. This will bring the Lexus Satnav up to date with speed camera, and speed limit warnings along with full postcode entries at far less cost than a map update without loosing in fact gaining functionality. Audio will also be implemented.

When I have a viable system up and running I will post details.

John.

@Britprius/John, just seeing if you saw my message above ?

I've not seen much else on the site regarding this, so I assume no one has attempted it yet ?

I'm interesting in looking into this some more and would be good to hear what how far you got with this.

Sorry for the slow reply as I have been away for a few days. I am still working on a realistic solution to the problem. I did have some success using a small TV main board mirroring the tablet or phone to this then using the video out to supply the OEM screen. This is cumbersome to say the leased. For those that have android devises with HDMI out it should be possible to use a HDMI to video converter, and injecting this into the OEM screen.

My android systems do not support HDMI so I am still working on it, and will post here as soon as I have a viable solution.

In what area of the Westmids are you in? Although I live in Herefordshire  I go over to Stourbridge at leased once a week,

John.

Hi guys,
              I'll add my two-penneth as I started this thread.

In the event I paid my £80 for the navigation update (half price) and got a decent cup of coffee and a nice clean car back too. It is something of a relief now to travel down the A11 and find that the sat-nav has me securely placed on a road an not in the middle of a field but I know it is only a matter of time before I'll need to buy a further update (at full price this time) or find some other navigation system.
I additionally bought from e-bay an inexpensive Bakeey NonSlip 360° Rotation Dashboard Car Mobile Phone Mount Holder GPS PDA to hold my mobile phone which, as holders for mobile phones in cars go, does a very good job. holding the phone in an excellent position for viewing above the cowl to the screen but it isn't that convenient to control and I haven't got a power supply to it. The mobile I own has good battery life and charges rapidly so the latter hasn't been a problem so far.

I also note that Beat Sonic now appear to make a screen mirror (ID   IF-04EP) for many Mk 4 GS models. Videos are available on the internet and I think I found a UK supplier while surfing on this topic (but I can't quickly locate it now). It was expensive but as I noted above so is buying navigation updates every year or so. I'd welcome a review from anyone who has purchased this item so that I can further consider this option when I feel the present built in navigation maps are beyond their useful life.

      Had my car a couple of months now and been generally very impressed, I don't know why these cars are not more popular, a lot of car for £5,000 !
      Anyway, the boot will not open using the button in the car or the latch on the boot itself (it will open with the key)
      I have checked the switch in the glove box and I assume the fuse is ok as the fuel filler cap still works and according to the manual it is the same fuse.
      Anyone got any ideas or come across this before?
      I did take out the Lexus warranty, would this sort of thing be covered?
      Many thanks.....

      Rather than keep updating my New Members thread I figured a build thread would be a more appropriate place to keep track of my changes. Especially as Robb/Mod's went to the trouble of opening up this new section for us.
      January 24th'17 - GS 450H purchased 

          
      This is my first Lexus, my first hybrid and it's such a joy to drive with plenty of power and it's very slick CVT gearbox.  For a big car it goes/stops and handles surprisingly well.
      The rear boot space was the only concern but with just me and mrsF it's worked out just fine and 6 months down the line we've made a couple of trips over to Belgium without any issues.
      So lets have a brief recap of the initial 6 months of ownership. 
       
      The car came with a spare key but it wasn't working, thankfully a new CR 1632 brought it back to life #phew      
            
      January 31st - Lexus Full+100 service @Lincoln, including a Hybrid health check - was successful and warrantied for another 12 months  
      The Lexus health check listed these items...
      both front tyre valves leaking - the OSF definitely is, around the base of the TPMS sensor. I can't see any leaks on the NSF rear brake pipe corroded - all I can see is a small rub on each side, looks like the inner arch has rubbed the pipes slightly front shocks leaking from body - all four dampers are bone dry tho! - I look forward to hearing what Lexus have to say about this exhaust blowing at 'Y' section - agreed, discussing this with the dealer that sold the vehicle exhaust also has a slight leak from the mid section - I couldn't get underneath sufficiently today to check this    Not the best of starts but I was prepared for some work to get an older car 'straight'.


      February 7th new wiper blades    
          
      Feb 11th, lowered bonnet bump stops that were preventing the bonnet from closing without a really good slam.    
            
      Updated the OEM satnag, using http://www.latestsatnav.co.uk/ - now the local roads appear. This supplier has the UK/Belgium/etc countries all on a single disk  unlike other providers or OEM (over several disks)  I needed to disconnect the 12v battery to get the replacement DVD to load.    
            
      Feb 14th, Dashcam fitted, a Thinkware F770 dual channel that I'd been using in my previous steed.  Hardwired into the AUX circuit via a piggy back fuse on the drivers fuse board. Earthed to the forward fuse board bolt. As the fuse board is well recessed, I've left the cover off for the moment but I may cut a slot in later and then refit the cover.

      Routing the cable was quite easy and only needed the drivers side end of the dash un-clipping.  The cable was then tucked in the drivers A pillar and roof lining, up and over to the camera. Excess cable was looped up, cabled tied and tucked under the carpet well out of the way.
      As the rear sun shade doesn't run parallel to the rear screen (it starts further forward in front of the 3rd brake light) I managed to fit the camera just above the 3rd brake light, higher would have given a better image but that would have interfered with the sun shade.

      The rear camera cable was run around the parcel shelf, up and over the rear door but I couldn't get a neat run around the top of the b-pillar.  So I dipped the cable halfway down the passenger b-pillar, popped off the lower section to loop up the excess cable (out of the way of the seat belt). The cable then went up and over the passenger door and around the top of the screen to the camera.  All neat and tidy (ignore the mirror that was just pushed out of the way to show the camera install).

      Test views, front

      rear

      Feb 15th, gave the headlights a quick polish to see how they'd come up.

       

      Quite pleased how they came our after just a few mins work.

      Cargo net fitted, under the parcel shelf so I still have easy access to the boot (like this sample pic)


      Feb 17th, the car has been up on the ramps today with my trusted local mechanic who gave it the once over with me. All of the shocks are bone dry with no signs of any leaks or misting ANYWHERE. So for now I'm going to ignore the Lexus recommendation LOL
      The exhaust is definitely blowing at the rear Y (see earlier pic).  We also saw that the OSR box has a few issues...


      Pretty obvious huh.  Neither Lexus nor the last MOT flagged it.  It can't just have appeared in the last 3 weeks since I've owned it.  I despair.  The rear section is beyond repair so I bunged my indi some beer money for using him ramps. Looks like I'll be getting a new rear section made up in the not to distant future 
      Feb 19th, new mats fitted, this Luxury version fits a treat http://www.ebay.co.uk/itm/252033676404

      Gave her a good scrub

      Including the engine bay, no treatment applied yet

      Turns out the passenger footwell has only been blowing cold, giving mrsF cold feet and making her unhappy. Before you ask...yes, we tried all options of Dual/modes/temps/etc. So after surfing for solutions I dived in to check the servos;


      Drastic eh. I eventually tracked down the passenger temp control (passenger side) but with the fixing screws out, I couldn't get the servo out :( With fading light I decided to button it all back up and went for a quick test drive. What'd'ya know, the passenger footwell is now working! The only difference is that I taped up the ducting, both sides, to get a good seal from the heater core. Result.
      The sceptic in me reckons it can't be that easy and that I'll be back under the dash before too long. Which is just as well as I have a few screws left over Never finish up a job in the dark!
      I didn't get anywhere with the heater on Saturday afternoon, so buttoned it all back up and thought the mode control was roughly working.  Nah, on a 5am commute the other morning clear screen setting kicked in (I didn't test that earlier) and the heater did zip all except vent to the rear seats! For the entire 4hr round trip
      At lunchtime I went back to basics and figured out what lever on the heater does what. I also removed the 2 servo's/mounting plate and let them do their thing.  Once I had a grasp of ALL the settings (temp, modes) I set all levers in roughly the right setting, lined the mounting plate to the heater arms (no easy feat), restarted the vehicle and the first test failed
      I have noticed that when you turn off the ignition, the servo's sit for a while and then revert to some standby setting.  I think this has been throwing me off so I removed the servo plate, set all levers in roughly the right setting again, fired up the ignition and let the servo plate settle.  With the ignition still ON, I aligned the mounting plate to the arms for the umpteenth time and gingerly pressed a different mode button...
      The first test worked and the servo's didn't bind. So I tried another mode setting and that worked.  Trying not to freak out, I carefully went through all the possible combinations and to my delight they all work
      The passenger side footwell output is still hopeless tho I think I may know which control needs a slight tweak but then it may just be the way the airflows. So rather than dismantle it all again I reckon I'll buy the mrs a heated blanket/mat or fan to keep her feet warm.
      To help align the 7? heater control arms to the servo plate I found one of these cheap endoscope camera's quite helpful to help see around corners http://www.ebay.co.uk/itm/122076843254
      Oh and this time there are NO spare fixings left over 


      March 9th
      Yesterday I had the...pleasure? of exploring Leeds city center whilst my car was left at Tony Banks for a new exhaust.  To recap the rear section had the usual split and a gaping hole in the OS muffler, so we definitely needed a new rear section.  I knew the middle section had a slight blow and when Tony removed the rear...the middle section decided to snap in two! He spent around 6 hours (elapsed) crafting both sections from stainless.  The cost of a new center section (with cats) was so tempting that I was already half tempted to get the whole lot done and then I'd never need consider the exhaust again.
      I didn't want any fancy or annoying noise so chose a standard set-up and driving around town you'd struggle to tell this system from OEM.  Under hard acceleration or at dual carriageway/motorway speeds there is a slight increase in noise, which is no bad thing at OEM is really quiet.  The system should quieten down a notch once it's coked up a bit.
      I didn't get back to the work shop before the car came off the ramps so I haven't had a close look at the system but from what I can see it looks dandy.
      The chaps were helpful and have plenty of varied work coming through the workshop, including a steady number of Lexus.  Overall I'm impressed and wouldn't hesitate to recommend http://www.tonybanks.co.uk


      March 17th OSR tyre flat - punctured, replaced with an Avon ZZ5, managed saved the TPMS and fitted a new valve.  OSF leaking needed which on investigation then a new TPMS sensor. 
      April 2nd, cleaned/lubed rear calipers. OSR stone guard is badly corroded 
      April 21st, paint correction/protection;


      July 6th, fitted 3M tape and a roof rack before the heavens opened. It'll allow me to get back on the bike and hit some nice trails, once I source a carrier.

      Found a great heavy duty bag to store the rack, http://www.ebay.co.uk/itm/263068408736

      Whenever I start my car the navigation screen greets me with the navigation menu which l have to exit out of if l don't want to use sat nav. 
      This wasn't the case with my Is and looks can't find anything in the menus to alter this. 
      Any ideas very welcome.

      I have some proper genuine Lexus mats in excellent, very clean condition in light brown/beige that were fitted my 2008 GS450H.  These were replaced by Lexus as a condition of sale as beige doesn't match the interior of my car - I got black instead.  I'm not 100% sure, but I'm sure they will fit any other GS from 2005 to 2011.
      I would like to swap for some similarly clean and tidy Lexus mats for a GS, but in light grey (my interior is Sussex Grey).
      Thanks!

      Evening,
      I've got a 2012 GS450h F-Sport and I have to pull the boot lid pretty hard to close it, should it have a soft close boot like my 2008 GS450h did?
