    happened several times throughout the day, always with the same results when pressing the on/off for the radio. Any ideas would be
    greatly appreciated. Thank You

    Re: Radio/nav problem

    There is a way to REBOOT all of the electronic modules in the entire car.
    Sometimes ( lots of times) that will fix random electrical gremlins.

    Remove BOTH battery cables... negative cable FIRST...
    Touch both cables together for 5 seconds or so, making sure they have good contact with each other.
    This will drain all the capacitors in the system.

    While you have the cables off... undo the one bolted to the floor.
    Take a little piece of sandpaper and sand the paint away from the attachment point.
    It will then have a better ground.

    Re-attach the battery cables... negative cable LAST...
    You will have to do the window EXPRESS UP learn again and you MAY have to do the memory seat settings again.
    Sometimes they will forget the seat settings and sometimes they don't.
