does this sound like a b.s. story or what.I took my 2006 2500 in today because the A/C doesnt work and my dashhawk says Im getting 14# of boost at idle and over 30# getting on the freeway.he said that they cant communicate with the canbus because of the after market radio anyone have any ideas?

Depends on how the radio is wired in. I'm running an aftermarket radio and they can communicate just fine. I had to spend about $100 for a harness to plug it in.

 

what harrness did you end up useing.Ihave a Peripheral CHYAH05,but I didnt hook it up yet.I was useing a 6502 Metra

 

I know on VW's this is an issue, removing the radio for the time it at the dealer should fix the issue.
