  1. I had much the same thought about dashcam power. I had a poke around the multi plug with a meter when I had it out to do the LED's but couldn't make much sense of it! I eventually settled for unclipping the left side A pillar cover and running my dashcam feed up inside it. Now I have a wiring diagram I may have to revisit the multi plug when I have some spare time. As an aside I wonder where the sensor is when a sunglasses holder is fitted? Or is that only in some countries without factory fit alarm? Andrew
  2. @Alfalfa You can check it easily enough, the door pops open just like the sunglasses holder version, it just doesn't have the finger recess, I just used a penknife blade and it pops open without leaving any marks. Andrew
  3. @Alfalfa As an aside, have you had a look inside your dome light panel? I saw that some versions have a sunglasses holder, but when I took mine apart to fit LED bulbs I discovered that in my 2007 IS250 the <Intrusion Sensor> is in the section which would be the sunglasses holder. I guess it's some kind of volumetric sensor? Andrew
  4. Funny you should post this, I was having much the same thoughts..... searching eBay for 'lexus 86790-53010' shows a few OEM cameras second hand from around £25 upwards. I can't quite tell from your pic, but is the connector just a single row of 5 contacts? All the ones on eBay that show the connector appear to have a squarish connector with 2 rows of contacts? Di you notice that the standard plastic panel (where the number plate mounts) doesn't have the central cutout that the cars with nav and camera have (different part numbers)? I use my Android phone with Waze in a dash mount and I think I've figured out how to automatically switch it to video display and back (my IS is a non nav poverty spec). I've just bought a cheapy camera to try with a USB OTG compatible video grabber (digitiser) that I already have. Andrew
  5. @gdh300 HaHa good one! I thought that the two terms were mutually exclusive, but German manufacturers however disagree! Andrew
  6. @Mauler Well it's a base model! Cloth seats, not heated or cooled, manually adjusted, no parking sensors. Yep, I'm surprised that the different country models are so different in firmware, you would think that they would program it for every country and just enable / disable bits of code as required. It's probably down to legislation as to what each market requires vehicles to do. Otherwise people like us could end up fiddling with stuff and then Lexus could fall foul of the law. Andrew
  7. Hi @Mauler Is that a .pdf of the UK Spec Manual? If so do you have a link you could share, I searched a fair bit but could only come up with the USA Spec one, which has considerably different customisation options to the UK one. I also acquired an OBD cable as my IS only came with one key and I needed to add a second hand key (from fleabay). Took a fair bit of messing about to get Techstream working, but the key added correctly, I had a prowl around the available options, there's only what's listed in the back of the manual, so I disabled the 'long press unlock winds down all the windows' which whilst it's somewhat useful in hot weather seems a bit prone to accidental activation which is very unhelpful! I also increased the auto lights sensitivity. Unfortunately options that the yanks get like auto locking the doors above 10 MPH and the like aren't available in the UK vehicle firmware. My IS is poverty spec so it came on 16" wheels, I was fortunate to pick up a set of OEM 17" wheels with tyres cheaply and as the 16"'s were worn out I got some Goodyear Vector 4 Seasons Gen 2 which although not full winter tyres like their Ultra Grips are however winter rated for european countries where winter tyres are mandatory. Last year on normal tyres it took me 10 minutes to persuade it over the little snow berm outside my garage and it wasn't much fun on the road, this year however no problem 'Snow Mode' on until I got to the main road and an easy drive. Andrew
  8. Hi @Mauler I guess there's a separate manual for the multimedia stuff as it isn't mentioned in the main manual. From the USA Spec manual that I found in .pdf form (I'm 6000 odd miles from my IS and it's manual at the moment, slumming it in a Toyota Yaris!) but I'm fairly sure it's equally descriptive! I got a set of 16" Goodyear Vector 'All Season' (snow rated for Europe) tyres on a spare set of rims in January this year, with those on and 'Snow Mode' engaged it made the couple of days of snow we had a quite enjoyable safe experience, I didn't really check what gears it was using but it's more of a 'low torque' setting. Andrew
  9. I'm fairly sure that those lock / unlock options are from the US IS250 Manual. US spec cars appear to have different firmware, they're certainly not mentioned in the UK spec manual. When I programmed a new key for my 2007 IS250 I also had a good prowl around in Techstream and couldn't find any trace of those options. Andrew
  10. Well, Fridays' weather made for a proper test, the difference over normal tyres is unbelievable! Snow mode on and just drive off like normal with no wheel spin, braking is vastly improved but obviously there are limits. There's a short sharp hill (Ashford hill) near to work and two cars were stopped and dithering so I just pulled round them and drove gently up the hill, fortunately there were several cars waiting to decide about descending, so I had the road to myself! You could easily lull yourself into a false sense of invulnerability there's so much grip! You still need to be careful with cornering and roundabouts. Andrew
  11. @Vintagesixtysix Haha! Same here..... going from cold stiff 17" tyres with 4~5mm of tread to brand new soft winter tyres with 8mm of tread is significantly quieter! Andrew
  12. Put your tyre sizes here and it finds '255/40R18 99V GOODYEAR UGRIP PERFORM G1 FP XL' £177 a tyre though! Andrew
  13. Hi Shaun, My IS250 is base poverty spec! So it came with 16" wheels (205/55 16" tyres). I picked up a second hand set of 17" wheels with summer tyres so seeing as the existing set of 16" tyres were done for and needed replacing I got the worn out tyres removed and binned before Christmas and gave the wheels a bit of a clean and fitted the TPMS sensors. Andrew
  14. Apologies for the tardy update, as we hadn't had any particularly cold weather prior to Christmas I only got around to getting a set of winter tyres at the beginning of January. As my previous Goodyear Efficient Grips had been reasonable and had worn evenly I decided to go with Goodyear Vector 4 Seasons Gen 2 which although not full winter tyres like the Ultra Grips are however winter rated for european countries where winter tyres are mandatory. They appear to have plenty of grip when it's cold and wet and looking at the forecasts It looks like I might get a chance to test them properly later this week, While I had the old tyres off the rims I also fitted a set of aftermarket internal TPMS units from eBay.
