i've just done the 'outfit my car' on crutchfield and it says "Your vehicle has no accessory power lead at the receiver. The integration adapter provides the accessory power you will need for your new receiver. PAC C2R-CHY4 $129.99"
i don't understand how there can be no power behind the stock head unit? i thought both radios would just use a standard iso connection? just to let you know, my GC doesn't have audio controls on the steering wheel so i don't need to take that in to consideration
at $130 for the cable and $150 for the head unit and a bit extra for the fascia, it's starting to get a bit expensive for a regular radio
