Very inflexible app Big USELESS logo on top left side on my WiFi device - would have rather had that space for some buttons instead. Can't change any of the main big buttons. Can't add speedometer to the main screen. Pressing home goes back to the default launcher instead of going to car home. Overall this app looks cool but is pretty useless. Also, looks like development has stopped, so no point installing this. I also wasted my $3 trying to write this review because there wasn't enough time for the refund. :(
Added: Support for WiFi only devices.
