Just an update for you. I went to an auto electrician (3rd time lucky, first 2 never replied). He Checked all fuses, tried a replacement multi switch, took door covers off and also the loom going through the door into the car and under the dash, checked wiring, and no obvious cause of fault found. Eventually he admitted defeat. sounds like it will need to go into a Lexus dealer. Am I correct in thinking they can plug in a diagnostic tester and it will pinpoint the issue?

I think the door wires is a possibility - though nothing has happened that should have caused them to suddenly break. I’m in Dorset and will seek out an independent who can take a look at it for me. I had initially wondered if others had had a switch failure

I’ve checked the manual- nothing useful, although I scoured what the fuses do, I could not see one that controlled the problem items collectively. searched US forum - info on resetting individual windows followed, no improvement. Nothing else useful found. Lexus dealer - quoted £140 per hour to diagnose with parts and actual repair time on top - realistic potential repair estimate of £500 plus. Said it would unlikely be a fuse, and suggested that the door multi switch part would cost about £300 (though they could not be bothered to actually look it up). Basically wanted me to pay for the diagnostic test and offered zero other guidance or experienced knowledge. so, I thought I had better come to this forum first. LagerShandy, thank you for your suggestions, appreciated.

Anyone got any ideas????

Hello all I have a Lexus RX450H, 2012. Yesterday I noticed that the door mirrors did not close when I locked the car, and also that there seemed to be a bit of a delay in locking/unlocking when pressing the remote. On further investigation, when I opened the car, the set of buttons in the driver's door were not working, apart from driver's door window. So: Door/unlock from inside - not working All passenger windows - not working Mirror Auto button - not working, no illumination Driver/passenger door mirror - not retracting Driver/passenger door mirror - not adjustable Driver's door window - working As far as I can tell, other electrical items are working fine (fuel release, audio system, sunroof cover etc all tested). My first thoughts are could this be a fuse? If so, which one? The manual doesn't seem to offer me any pointers. Any other thoughts anyone, please?

Hi Dan and Jason Thanks for your replies. I don't know anyone with an Android phone that I can connect to the system, but note that Jason has the same issue. I've had different iPhones though, and they all do the same (oh, and you can't download your phonebook from the iPhone to the system either!).

Hello I've had my RX400h for 3 years now, and have been generally pleased with it. It has been very reliable, but 2 things really annoy me, and I am wondering if anything can be done: iPhone connectivity via Bluetooth is very hit and miss. When the phone does actually connect to the system (it often fails to connect), there is something that I have not ever come across before - if dialling out, there is never a ring tone heard. The radio keeps playing until the phone at the other end is picked up, then the radio is muted and conversation begins. Is there any way to change this behaviour - it is very disconcerting! Secondly, is it possible to connect a Pure 300 DAB system to the Mark Levision system ? There is no aux input as such.

Hello Everyone, I have recently purchased a 2006 Lexus RX400H from a Lexus main dealer. It is my first Lexus, and I am new to this Club. Whilst overall, I am very pleased, a few things disappoint me a lot: 1/ Even though I have 2010-11 maps, I cannot update my destination choice on the move. I have read through the forum postings here and others seem to be doing that via firmware update. How do I access the firmware update? The discs came from the supplying dealer, and are definitely genuine. I took the disc out, and reinserted it, but no firmware update option is visible anywhere 2/ On FM, whenever we switch on the rear window heater, there is a huge deterioration in the signal quality, with a lot of interference. Any thoughts? I tried uploading a video file to this site, but I am not allowed to do so. 3/ The Bluetooth implementation is just woeful. It seems that there is no way to manually type in names/numbers, and, as has been documented, the Bluetooth doesn't work with transferring data from iphone. According to the Lexus site, the Galaxy S 11 works perfectly, and I managed to borrow one, setup a Google account, backup all my vcf files from iPhone, transfer those to the galaxy S, connect to RX via Bluetooth, then after a struggle, managed to get the names into Phonebook 1. Alas, I soon realised that if a contact has more than 1 number, only the first number in the list is copied. eg, the home number, but not work or mobile. How useless is that? To discuss the above, I contacted Lexus Customer (non) service, who had no clue how to answer any of the above. They directed to a Premium Rate telephone number for Technical help (they initially declined to tell me that it cost £1.50 a minute, even though I asked). For a Premium Brand, I think that is disgusting. I did ring the supplying dealer who had promised to look into it for me previously, but, weeks later, I have yet to hear back from them. So, as I use the phone and sat nav a lot, it seems that paying a premium for the integrated systems has been a total waste of money. I am considering getting a Parrot fitted, can anyone confirm that I will need just the Parrot and the SOT lead. Do I need anything else? Will I retain the full functionality of the stereo steering wheel controls, as with other cars? I guess getting a Parrot with music playback will enable me to play music through the Mark Levinson stereo somehow - or will I need yet another interface? Thanks for your anticipated help.
