I have a 09 Journey with Req Radio I would like to know how to hook up a
monitor to the radio itself, know it can be done but. Can't seem to figure
out exactly what pins I need to tap in to. i hve found some good info but
its also contradicking. I was told just hooking up the positive off an rca
cable was all I needed. but I have tried this and doesn't seem to work. I
believe the positive has to be hooked up also? if anyone has any info on
this or has done this it would be great! thanks...
