I did not apply the firmware update on my radio, as the date on my firmware was later than the date on their update. Before they released the firmware update, I solved the problem of it not going back to the rear camera, by cutting the orange trigger wire in the back of the radio. This also solved the problem of it muting the sound when the turn signals were used. The orange wire is the reverse positive wire, thus if I go in reverse, you have to manually select the rear camera. This is not normally an issue as I normally always have it set on rear camera.
