I’ve got a 2014 Mazda 6, it was probably a weekly occurrence where trivial events (calls, song changes, phone connect/disconnect, etc.) would cover up the feed as I was actively backing up. Since common sense has failed manufacturers, is there no regulation (US) to mandate an uninterrupted view? I’ve had to turn off Bluetooth whenever reversing, which creates another problem by distracting myself futzing with the phone.
