Gmos01 will work if your not using the factory amp and your running all new speaker wire...

You really don't even need the Gmos01 because you can hook the red accessory wire from your new radio to a thick gauge yellow wire in the passenger side fuse box. It will act exactly the same as the original RAP circuit that a Gmos01/04 would provide.

Don't use the Metra/Schoche/PAC modules you will have communication errors. I really wouldn't even bother wasting your money on any module.
