I had an after market JVC radio installed in my 2008 Ram that came out of a 2007 Ram. The insturment panel gauges go all crazy and ding non stop.
Changed the module in rear of radio to 08 from 07 model and same thing
happens..I can undo negative battery cable and re connect and everything
works fine until i turn truck off and it happens all over. Radio always works fine
its the guages that are the problem. I even had my ECM reset and did not
solve problem..Help
