i have a 02 max with a factory nav system and the nav controls the a/c. i was trying to put a aftermarket tv in there but wanted to know how could i control my a/c. Has anybody had the same issue

 

I actually just got an aftermarket deck put in with my full system and all he removed was the radio that has the tape deck my nav still works and the voice control alPpppso for my nav
Still works...... It took alot of time and patience, but it can be done and by the way its an aftermarket DVD player that was installed beneath the nav.......

 

Thanks bro
