hey guys sorry I'm new here. i checked around search did find some answers but ill ask the experts now. has any one had great success retaining the the rear controls and head phone jacks with aftermarket decks also if its works easier i would also just be interested in swapping out the old cd/tape deck to the hem gmc navigation screen if its just plug and play as i can just stream the audio from my phone to the fm transmitter with good enough quality for me
