I have a 06 RRS Supercharged. I am replacing thr radio with a aftermarket Pioneer and the diagnostics, nav, and 4x4 upper display will not turn on with the aftermarket radio harness. I would like to still monitor the 4x4 and ride height. Can anyone help me with this or provide me with a wire diagram for the radio and diagnostic screen? I am guessin the 2nd radio harness that is not plugged in now sent power to the upper screen. Other option I saw was to dismantle the old radio and fit the circuit boards plugged into the old radio boards hidden in the dash but there has to be an easier way...
