thats a very good question. im not sure of the answer.

i know that the connector from the truck plug into it and then you have to soughter the cables coming out of the module with the ones of the nav unit.

i think you can, but you will need to know which wires are which, you know speaker wires, mute wire and whatever else there is. unfortunately i dont know what would be the best way of doing this. maybe someone that has done this already will pop in.

i agree that if your not using it spending the money is pointless.
