i got one of those navitouch systems on ebay and am having a heck of a time with it.
right now, the biggest issue is the cd/dvd reader won't turn off when you turn the car off. It will only turn off if you manually turn the unit off. this is causing the battery to drain if you forget about it.
the manufacture said the problem is becuase of the cannbus system. Basically, they're no help.
i'm thinking that the way it's hooked up now, it's getting a 12v+ somewhere that won't allow it to shut off. Is there a ACC wire somewhere that i can hook up to this to turn it on/off with the car?
Yeah, someone wired it wrong. It' should have a separate power wire that is connected to a 12v accessory wire that tells it to turn off when the truck is off. Did you install it? What wire harness kit did you use?
