So...Avic works well and everything is doing what it should; however, when I turn the car off for more than 30-45 seconds, everything resets. I mean, the illumination is cycling, the radio presets are gone, the navi is all reset, everything is back to initial startup! Any ideas what is going on? The funny thing is, it remembered my 'home' setting, but nothing else! Shouldn't it retain everything via the constant +12V supply??? All my wiring is soldered, and trust me, I've been soldering for years...there's no way anything came undone.
