I had seen on here someone had a link to a place that sold radio adapter plugs for aftermarket radios , not the $130 ones , it was like $20 , anyone know this site ?

 

Not exactly the price you are looking for but

Amazon.com: PAC C2R-CHY4 Radio Replacement Interface for Chrysler: Car Electronics

Its certainly cheaper off of amazon then most places.

 

Be careful with the PAC on a 12. The shop I had install my head unit went through 4, and the last two were different than the first two but all had the same part number. Seems like the new computers/wiring with the infinity amps on the 12's have caused PAC to change something (at least this is the line the shop used) but I can say for sure that there is different parts with the same number from what I had in my hands

 

I used the PAC but I think the metra option is a bit cheaper, check out the XSVI-6522-NAV
