I had an aftermarket stereo installed in my charger a few years ago and I don't think tht the shop installed the bypass harness for the computer. I have a DTC code showing "lost communication with radio" is this code the cause of tht? And if so does this affect my car any other way? The stereo works fine because I have a full Kicker system as well , wat I'm asking is, is this affecting the way my car runs or performs or is the DTC code it?
