I am trying to install amps and subs in my truck but the new dodge rams looks so complicated to work on. the dash board is crazy i don't know where to start in order to take out the navigation system to reach the back and install my RCA cables. that's the only problem; getting behind the head unit and running the RCA cables to install the amps. any idea how to open the dash board area in order to remove the navigation???? PLEASE HELP. COMPLETELY LOST!!!
