Well I have given up on the Clarion head unit, I went to
Crutchfield and got a new
Sony CDX-GT805DX.
And a steering wheel control interface for Pioneer and Sony, a
PAC SWI-PS. The Pathfinder has some proprietary closed source hardwired steering wheel controls that will only work with the Clarion
A
Scosche OEM Amplifier Adapter to work with the BOSE amp.
And, of course, Nissan being so screwy, I had to get a friggin' "Diversity" antennea adapter. Leave it to Nissan to take something as simple and standard as an antennea and bastardize it. I wonder if Nissan is a subsidiary of Micro$oft?
The antennea adapter may actually work out for hooking up the SP-716 so I may be able to tune in TV stations. Crutchfield threw in wiring harness adapters, mounting brackets , the antennea adapter along with instructions and $20 off of Scosche OEM Amplifier Adapter that I had to have for the Bose amp.
Everything should be delivered Friday. Hopefully I will have sound this weekend!
