when i started my car this morning my avic n2 didnt work so i unplugged it and plugged it back up again, and it started working. Then i shut my car off to get a haricut and it was working fine. THen i took a shower and i started my car and now it doesnt work. It flips out like it resetted only nothing shows on the screen and none of the buttons work not even the open/close button. The only button that works is the Eject button to eject cds. ANYONE HAVE ANY IDEAS PLEASE HELP!!!
