The lack of adapter cables for using the SR10 with On-Board/OEM systems is fairly easily solved by using a SA-0016 bare ended cable and the appropriate DIN connector for the 5, 6 or 7 pin connection. We have successfully wired these into a GoldWing and J&M 2003 systems by pairing up the audio, grounds and mic wires, while abandoning the PTT wire (has no where to go!). An open channel needs to be established, but after that all functions c/b, radio alternate feeds and BT-phones are working. Diagrams are readily available!
