I’m having an issue with my whistler scanner, the head unit for no reason stopped working, no display no lights no nothing, when I went to sleep after turning the scanner off woke up 8 hours or so later tried to turn it on and nothing, I’ve tried everything I could think of to get it to work, when I plugged into the usb jack to charge the inside battery I could hear audio just can’t control nothing, or see anything, Does anyone have any ideas on how to fix this?
