Got it back in 2007 brand new, turned it on tonight and it was all messed up. No sound, and kept showing the voltage meter. Then alerted to K band and wouldn't auto mute and no voice alerts once I turned the sound back on manually. Still detects radar just in a strange way. I try to do the program buttons but all I get is a noise that sounds like the laser alert and it doesn't let me get to the program settings.
Radarrob also tried to help me out going through the factory reset but it doesn't seem to be working. Any last thoughts before I send it in?
I have had some epic saves, and some scary saves with this detector, so I am going to keep it. It's an M4. Off axis = SCARY, but it's hot on Ka Band.
