OK, after much thought I went down the Android route, if I understood everything correctly is as follows:
1/ Android is supported ?
2/ No driver downloads required?
Either way, I've just plucked up enough courage to try a connection, firstly connect all the cables, open the app, allow for a connection for the app.
Hey presto it all seems to work, did not go any further at present, not even started the bike. So just had a quick look around, my tune is 20712 what ever that is, more reading to do regarding maintaining a good voltage to enable minimum connection issues, which fuse to pull etc etc......
Scary stuff for me this, unknown territory
