    I successfully used my 940 Live last night and reached my destination. When I tried to switch it off the screen displayed some sort of system information which remained until the battery run down. when I connect it back onto the 12volt and switch it on I hear the startup drum beat but all that is displayed is the tech info. How do I cure this?

    It sounds as though your power button is stuck.
    Normally (though you've probably never had reason to do it) if you hold down the power button long enough during startup, you will see a white print on black diagnostic screen.
    You'll need to open up the unit and 'unstick' the power button. Use any of the several tutorials on replacing the battery to see how the case opens, if you're not sure about it.

    Thanks for your response. I saw a thread suggesting using a little WD40 dribbled into the switch and gently operating the switch a few times to release it which I have done successfully. I will no doubt have to dismantle the unit in the future but for now its working ok.

    Hmm.. wonder what kind of muck got in there that WD-40 could resolve?
    Glad you've got it unstuck.
