Has anyone analyzed the protocol to the CB or the CD changer? If you have a protocol or logic analyzer at hand, would you be willing to acquire the traces?
The 2004 Honda Goldwing GL1800 6 CD Changer has the following pinout on C32 (coalesced schematic information from Service and ETM manuals):
1 - Bus B/U
2 - Bus Sys Acc
3 - Bus GND
4 - Bus Shield
5 - Bus Rch+
6 - Bus Lch+
7 - Bus B/U
8 - Bus Illumi
9 - Bus +
10-Bus -
11-Bus Gnd
12- N/C
13-Bus Rch-
14-Bus Lch-
Where shields on pin 4 protects pins 5, 6, 13 & 14
shields on pins 3 & 11 protect pins 9 & 10
The communications is supposedly a `Honda Standard' for the Bus+ and Bus-; but have found no details on that standard. I have hopes that one could interface a popular MP3 player with the controls feeding back for selection (a vacuum in the market is now identified).
The 2004 Honda Goldwing GL1800 CB Radio has the following pinout on it's interface cable (coalesced schematic information from Service and ETM manuals):
1 - CB Mic Audio
2 - CB Mic GND
3 - CB SI
4 - CB Audio
5 - CB Audio GND
6 - CB Starter Mute
7 - CB DET
8 - CB SCK
9 - CB PTT
10-CB Shield
11-CB Audio Mute
12-CB SO
13-CB PERM
14- N/C
Where shield on pin 2 protects pins 1 & 9
shield on pin 5 protects pin 4
shield on pin 10 protects pins 3, 6, 7, 8, 11, 12 & 13
Unsure what some of the signals do. CB PERM? CB Audio Mute (does it mute the stereo, or is it the reverse to mute the CB)? and CB DET (maybe this mutes the stereo)? But the necessary communication Protocol would transpire over the CB SCK, CB SI and CB SO lines. My hopes are to connect Cell Phone, GPS, FRS and/or HAM equipment up instead of a CB.
I know, purchasing these components if I can get the logistics of also procuring a logic analyzer, then later selling the components on eBay is an option. But one hopes for easy/cheap wisdom first. Never hurts to ask ...
