Finally! Received the Aerpro control harness (CHLR10C) to make my Alpine ILX-702D head unit compatible with the MOST system.

It is working but at the moment I haven't got the steering wheel controls, reverse sensors, dash clock or CarPlay.

However I'm out the door in half an hour and heading bush for two weeks so I can sort that later.

A bonus was being able to use the OEM mounting hardware so the unit is well secured.

All the speakers and the sub work so look forward to experimenting. MY11 SD4 SE Auto
