Re: PAC C2R-CHY4 aftermarket radio harness problems. Need some help
PAC has newer versions of the interfaces, I'd try one of those if I were you. If you want, I can take a look and see if I have a spare laying around you can try.
2015 Billet Silver
2012 300SRT, 2009 Jeep SRT, 2006 Charger SRT
Too many mods to list for each, so let's just say a lot was done over the years.
