This morning after starting my 05' RX330 I noticed that the Nav screen was blank. No "I accept" screen, nothing. Pressing a few of the A/C buttons I found that some did nothing at all, and some functioned, although their functions were very different than they should be. No Menus, no trip info, no climate control screens, just stereo control / station info screens that I never used to have at all. It seemed as though only the stereo is linked to the display now, which it never used to be. Then, pressing the "A/C off" button brought back the GPS map.
Weird enough, I thought, as I started out on a 2 1/2 hour trip across the AZ desert. Then, after pressing the Climate Control button, (huge mistake) my wife's side went to full cold A/C, and mine to full high heat with no way to change it. 2 1/2 hours later I wanted to drive this stupid car into the CO River.
Anyone with any similar symptoms or suggestions? I can't find anything similar searching the web and kind of need to know where to stat with this problem.
