Unreliable product, poor support- great idea but implementation is 3rd rate
16 months experience with 2 cars. Unreliable product. Have two of these one in a Lexus and other in Acura. The Lexus version frequently rebooted for no reason and lost connectivity. During a 4 hour drive I had to stop/start car 5 times to reconnect the phone. Per support I swapped frequency used by device. It has reduced random reboot but still occurs while driving. On the Acura when I upgraded to latest iPhone it started to reboot as well. Support responds with cryptic delayed messages to upgrade OS that does not work. Now one box is unusable. Additional issues include the box failing to start at times, using WiFi to connect that drains phone battery and expensive installation. Not worth it. Was better with my old nav systems.
