Everything is back to stock. THe headunit is out of an 06 which I assume is the problem. But the HIFI amp is back in place where it should be. I do have aftermarke speakers but I can't imagine that would be the issue as they work great for music. I understand the PDC sound changed from earlier to later. Buzzer to chime. I am trying to hunt down somebody local with an 09 so I can try their headunit and see if anything changes.
Seperatly if I run a acc power source to pin 13 while running an aftermarket headunit will my radio reception be better?
