Hey folks - new to the forum - glad to be here. I've had the 78 for several weeks now and it worked like a champ until last week. Now after the self test it immediatly starts alarming Ka band at various levels and just doesn't stop. On occasion it appers to work normally. This malfunction shows up in multiple locations and only upon starting up the unit. Very frustrating - it's a great unit that I think is now broken??? I have a hybrid Camry - could any of the EMR from the power control module be screwing with the detector??
