I have a 2004 w/42,000 miles and have not experienced the issue you stated. In fact, I just recently programmed my moonroof control button to be an "auto" switch similar to the driver and passenger windows.

I have not had any issues with my navigation as of yet. I'd be interested to know what the issue is after you get it looked at by your Lexus dealer.

I don't know if your warranty company is a good one. I purchased the extended warranties for my wife's 2002 Mercedes ML320 and for my 2004 GX470 from Carmax and am pleased with them so far. We had to use the warranty on my wife's car for a sensor under the brake pedal. We took it over to Carmax and they wouldn't touch the issue because they originally thought it was a transmission issue. Carmax then called the local Mercedes service shop, had it towed over there, offered a rental car (We didn't use it becuase we were going out of town the next morning), and the car was done by the end of the day. We originally thought it was going to take two or three days with the car having to go to the Mercedes dealership, but were pleasantly surprised with the results. And all that for $50. Not bad...
