I updated my maps and the latest firmware was included on the SD card. I got a really good deal I think I paid around £65 on ebay.

Are UK screens having the same issue? They fixed this with an updated coating in 2015. BE-0090L-0915_IR (navigation screen peeling).pdf

Scotty Kilmer on his youtube channel and website. He's been repairing cars for around 50 years and knows what he's talking about with lots of practical advice based on his experience. Ask him which car to buy and he will nearly always say Toyota! He owns several cars one of them is an old Celica with over 250K miles that still shifts perfectly. He bought his wife a Lexus. http://scottykilmer.homestead.com/

That's a good idea and I'm glad I discovered it. I will probably use it when I'm on holiday. East midlands is fairly flat so I will keep it in D most of the time. It's good that it cancels again by itself. I thought it might have also given a low gear when climbing a similar hill. Maybe it's not such a problem now autos have 6 gears. In previous Hondas or Hovers (Honda Rovers) D3 would also provide extra control preventing the box from repeatedly going up and down through the gears when climbing a steep hill as if it couldn't make up its mind. Then switch back to D for normal driving with overdrive. The Lexus handbook could be clearer, it does mention to prevent unnecessary up shifts, how many upshifts to you have when braking? It's almost as if they hadn't finalised the feature when the book was written as it also mentions 'a certain amount of time'... It's not a problem now I know how it works, it's easy enough to select Manual mode when I feel the need for greater control or overtaking. I'm impressed with the ride and how smooth the transmission is.

New SD card received. Installed and working, it also updated the Firmware to VD12104A at the same time.

Dislike 1. Standard light bulbs for interior light and boot. I thought these would be LED. Not sure how bright the boot light will be when needed to be used in the dark winter months? 2. Firmware update is dealer only in the EU for the Nav system. 3. DAB aerial is on the rear window, the reception could be better around here. I wouldn't have minded a good aerial on the roof. Having said that it does work surprising well for a window aerial. 4. Glove box size. Not sure I will keep both handbooks inside it, not much room left if I do, Like 1. The look of the car, great styling! 2. Build quality including the interior. Looks so much better than Infinity. It feels and looks premium! 3. The Premium Nav and sound system is really good. Not perfect, could be better but works well for me. 4. The ride, very little body roll. Turning circle. Smooth and quiet. Very comfortable interior. 5. Reliability. 6 . Lexus dealer support.

You're right. It works as you said, it's only for engine breaking. The handbook isn't clear and misleading when it mentions to avoid unnecessary upshifting. Might be useful going down a steep hill to save the brakes.....

Thanks I will give it a go. The manual also says "preventing unnecessary up shifting". Remembering my old Rover 620 (on my IS300 I used D or manual only), it had D and D3. D3 would not allow the car to go into overdrive (4th top gear), you could use it to drive up a steep hill or going down one, also good for twisty roads. The car is going into MK Lexus for the wheel arch recall on Wednesday and under guarantee with Arnold Clark so I'll have a go and see what Lexus say.

Thanks for the reply I was maintaining 23 to 35 MPH, so the accelerator was slightly open at the time I selected D4/D5. Do I need to take my foot off the accelerator, select D5 or D4 etc, then apply the accelerator? This would seem to imply that it is only intended to slowing down? It changed from D4 or D5 back to D after around 3 seconds of use, the period of time cant be 3 seconds? I would have thought a few minutes? I might need to try this again tomorrow. The car drives fine, manual modes works well as expected. Car has only 4000 which is nice and low for a 2014 car. I might not have been going fast enough for those gears?

So I thought I would try the Auto modes where you can stop it going higher than a certain gear. I fully understand the idea, I normally use this features on twisty roads to stop the gearbox from constantly going up and down. I selected D5, the display changed as expected. I got the impression the car down shifted, then after around 3 seconds the display changed back to D (no D5), I pressed the - paddle again and it showed D5. then back to D. I then tried moving down to D4, the same thing happened, display changed back to D. When I pressed the - paddle again it showed D4 (not D5) so it had remembered that I had selected D4. I was expecting the display to show D4, D5 etc until I held the + paddle to switch back to normal Drive. Am i doing something wrong, does the display show D when D4 is selected?

My understanding is there is some kind of protection on the card, it then pairs with the Sat Nav on insertion. I have read elsewhere that used cards don't work for this reason. It may be possible for a an experienced hacker to copy the card? I suspect these are being sold off as we are approaching the changer over to the next map update. These will soon be considered 'the previous release'.

I've just ordered PZ445-US335-0M Premium Sat Nav Maps for £60 and thought I would share the link. http://www.ebay.co.uk/itm/LEXUS-NAVIGATION-PREMIUM-MAP-UPDATE-2017-SAT-NAV-SD-CARD-PZ445-US335-0M/272770589921?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 There's buyer protection so it looks like a good deal!

My reply from Lexus, basically sorry dealer only... Dear Mr ********, Thank you for your email regarding your Lexus IS250. I have read your email and it appears you want to update your firmware for your multimedia system. Unfortunately at the Lexus Head Office, we do not provide firmware or website links to download the firmware for your vehicle. We used to provide map updates on our previous website until Lexus decided to revamp their website, the new revamp of the website has removed the e-Store which was included in the previous website as there was constant complications with our website. If you are interested in updating your multimedia system's firmware, you would have to visit your local Lexus dealership as all the updates are done at the dealerships. I hope this helps. I do apologise for the inconvenience this has caused you. Kindest regards, Moses Moses Matovu Lexus Customer Services
