First thing only connect with android phone , not for iOS. (As described in listing) Not much can do with this . It’s like other cheap available in market . Free app available on Android always comes include adverts (which is pain )
Works well, not just on the Audi but a Renault Clio and a Hyundai Coupe. It does the things I need it to and most of it from my phone.
Every tool box should have one.
