Hello,
My 2002 LX470 has this intermittent issue where the following things happen -
- touch screen doesn't load, black screen
- when I access climate settings, I see a message - Check connection of air conditioner
- Audio is switched off
- none of the touch screen related controls function properly
- when accessing the system is slow to respond (lots of lag before I hear a button beep)
- the AC works, it blows cold air, I'm presuming just using the previous settings, but the touch screen and physical buttons are all off so can't really do anything
Besides this, I haven't noticed anything else not working. I've checked the fuses, and they seem to be fine. I've checked for water leakage, and the car seems to be dry throughout. Also the issue seems to come up after somewhat extreme weather conditions - either a lot of rain / humidity or after a lot of heat.
I also have a BT45-TOY installed for bluetooth.
I've browsed several forums for this issue, and there seem to be quite a number of posts related to it, but haven't come across a single thread which clearly mentions a fix. I'm referencing the posts here in case someone else tries to do a similar search.
- mentioned water leak as a potential root cause
- another thread on similar issue which I don't fully understand
- external system not connected / check connection of air conditioner, 2005+ model, potentially an issue with an aftermarket device (VAISTech) install.
I will be opening up the nav unit and check to see if the BT45 is causing issues, but I just wanted to post this in case a kind member takes pity on my noobness, and helps me out with a known fix. I haven't been able to deduce anything substantial from my searches.
Thanks, and appreciate your help with this!

Nav Unit "check connection to Air Conditioner"
