Thanks all , yeh the install went well , worked first go
some tricky parts if anybody ever gets one I'd be happy to provide tips ! The most fucked thing was that BMW instructions required 2 wires to be tapped behind the obd2 port for power. These power wires do not exist on AUS delivered cars. Had to wire it up onto the cigarette lighter under armrest! I found a post of another guy in the states who ran into the same problem.
Pictures to come tomorrow
