Cd400 to nav500 upgrade.

An aftermarket radio will not power the factory radio controls as they are wake up via wake up wire.

All inputs are then sent via one wire to the radio BCM etc.

Hi Rusty, 

I have been doing some research and found out that the aftermarket radio unit will work whit a CD400 console so I wanted to try to change my wiring diagram from a CD500 model to a CD400 model. Only thing that I need to change is the last pin connector that goes in the console unit because there is a difference between a CD400 console and a CD500 console. So can you maybe give me a wiring diagram for a CD400 radio unit so that I can compare that whit my unit. The reason that I want to do that is because I bought a second hand CD400 console unit. So I could get some info about the wiring of the last part then I can make it work I believe because the aftermarket radio CANBUS firmware is compatible whit that CD400 console unit, now only need to know which connectors I need. I know that a CD400 console has 3 pins that needed to get connectec comparing whit my CD500 console that needs 7 wires. So I believe I need to modify that connector to a CD400 unit and it should work. I hope you can help me out whit this struggling months already and dealers are not very helpfull whit the aftermarkert radio units so getting info from then is not easy unfortunately.

Kind Regards
