Car has Bose system, and did have Navigation system, now swapped out to a CDR24 (shows Protect Code). OK, so I look in the front trunk and find this (see pic). There appears to be an optical jumper on something, and extra plugs hanging there?
Can someone tell me what I am looking at? I can't find a good wiring diagram for this, and suspect the optical goes to the CDC-4, and the rest is from a removed phone system, or something?
