suxel430

Problem resolved!!! Tested the battery, and it was indeed dying – had less than a third of the original crank power left in it. Replaced the battery: along with the car starting much better now, the L/R issue went away. It’s been consistently behaving correctly for over two days now. It is strange that the only obvious electrical symptom was associated with the L/R switch, but several mechanics confirmed this is indeed one of the outward signs of a battery going bad. Go figure…

I have been experiencing a really weird problem for the last few weeks on my '06 GS430 and haven't found anything similar anywhere... The L/R sideview mirror selector resets itself to "neutral" (i.e. neither side is selected) after the car has been shut down for some time. By "some time", I mean if it's in my garage overnight, then the next morning the L/R sideview mirror selector will reset to neutral. If I set it, drive to work, and then later go to lunch, it will maintain the setting. So I guess, after 8-10 hours it will definitely reset, but if it's 3-4 hours, it will definitely maintain it. Not sure what the exact time break between reset / not-reset is, but you get the idea. Besides this situation being highly annoying, the "neutral" setting for the L/R switch also disables the sideview mirror tilt when reversing. The *only* thing I've noticed different about the car around the same time the problem has started is that I think that my battery is getting weaker (it takes a few more turns to start the engine than usual). I haven't had a chance to have the battery tested yet, but was wondering if folks out there: 1) have seen this L/R problem before; 2) think that it could be related to a weak battery (all other electrical systems operate fine). Any thoughts/comments would be highly appreciated.

Thank you. But I am not looking to replace my navigation system, which is what the site you suggested focuses on. I am only trying to figure out how to update the maps and which DVD to get for the existing unit.

How do I update maps on a 2006 GS430? The current version info provided by the navigation system is here: I know I need to get a different DVD, but I have no idea which one. Sorry for such a naive question.
