Apparently the factory radio is tied to the navigation and the A/C fan controls. There are 3 or 4 plugs into the back of the radio. If the plug that has 2 wires is unplugged the A/C and Nav do not work on the separate touch screen. The 2 wires read approx. 2.4 volts each whether plugged in or not. These are likely a data type connection.

I'm hoping someone on these forums might have found a way to replace the radio on these vehicles. My customer wants a new amp and a new radio, but short of relocating the stock radio, we aren't sure if this will work.

Any info appreciated.

Thanks!
