Thanks for the feedback.
@turtleattacks: did you have any initial setup problems or did it work straight out of the box?
I have tried removing all connections, rebooting the phone and re-doing the setup, but had the same experience (worked first time then wouldn't reconnect). Good idea on the software front, but there doesn't seem to be any companion app that I can find.
Do you think it's worth seeing if there's an update to the firmware? I've found a video (https://www.youtube.com/watch?v=aEre5-h_EVI) that explains the process (much better than the instruction manual does!).
Another option could be to see if I can find another car with wired AA and test it out but don't think I know anyone! (Kinda wish Tesla would provide AA/CP support...)
Absolutely no issues out of the box. I should mention that we use it with Apple Car Play though.
I've also tested it on a Jimny and it worked well also.
I noticed that you can buy the product from Amazon so it's probably worth buying it from Jeff and have a good return policy. (Rather than buying it from some mysterious factory in China)
