when i turn on my MS609 all it does is Squeal ,does this need to be reset , it was just taken outta the case for the first time and has a fresh Battery
Reply to 2 floor: I tried to power it down and then power it up while connected to the vehicle and it still does the blank screen and SQUEAL , i have also hooked up to my PC and it does the same thing plus my PC does not recognize it as a device
