Honda Music Link

The Honda Music Link communicates with an iPod at 9600 / N-8-1, and I can successfully sniff it.

Eg: 000043 17:16:12.750 FF 55 04 04 00 29 04 CB FF 55 04 04 00 29 01 CE

This can be looked up here: http://ipodlinux.org/Apple_Accessory_Protocol

UPDATE: As an exercise to myself, this is as follows:

FF 55 – Header
04 – Length of Command
04 – Mode 4 / AiR Mode
00 29 – AiR Playback Control
04 – Skip– Command
CB – Checksum calculated as: 0x100 – (FF + 04 + 04 + 00 + 29 + 04)

FF 55 – Header
04 – Length of Command
04 – Mode 4 / AiR Mode
00 29 – AiR Playback Control
01 – Toggle Play / Pause
CE – Checksum
