Sorry if this is redundant, I searched for 3-4 hours last night and came up with nothing conclusive. (there are all kinds of threads for AUX port adds on the 6 disk with XM) I have an 04 GTP with the 6 disk and no XM, does have onstar. Want an Aux port. I bought a Scotche FM unit that wired inline with the antenna cable. Sound like bad AM and gets worse over the course of an hour or so. I am ready to punt to an after market. I know I will loose the door chimes and steering wheel buttons. My main concerns are below listed.
1. will this adapter work? Amazon.com: Metra TurboWires 71-2003-1 Wiring Harness: Car Electronics
2. Can the line out levels from an aftermarket feed into the bose inputs ok? If not, will a LOC converter / adapter allow that?
