“CLOCK DOESN'T WORK PROPERLY I have the KMM-BT312U product. I installed it pretty easily and set everything up, however, the clock doesn't work properly. After going to function, clock, clock adjust and putting in the time, it initially shows the time that I put in, but within a few minutes, it reverts back to about 36 minutes from the time I put in and this "gap" will be maintained. Even after turning off engine and restarting, it still maintains a time gap of 36 minutes.”
