Mine wouldn't work with AA at all, with or without cable. But after an AA update to my Samsung Galaxy S7-edge, I happened to try it again and with the cable it worked fine. After that it works with AA without a cable. Messed around a bit with AA and decided that in the USA, it is worth less than UVO, which is worth slightly less than nothing. However, the car is quite satisfactory as is. If it were possible to remote start it from a long distance or lock / unlock, possibly put the windows up / down - would all be kind of handy. Having never had them, I'm not dependent on them.
