Field notes
The described setup uses a phone mount and a connection to the car stereo, with the app calibrating to the mount. The listed controls go beyond choosing a sound: a studio offers separate faders and a three-band equalizer, while the workshop is presented as a way to build an engine. The page also says Live Drive stops when car audio disconnects and restarts when the same car reconnects.
