When I connect my device in the car the Tomtom drums sound, then seems to get halfway thourgh a beat and it just repaeats; like a cracked record. Then it turns itself off. There is no such issue when I connect the tomtom to the PC.
I've tried a reset.
Software is up to date.
Battery is full charged when I have attempted all troubleshooting.

I've tried holding down the on/off button, whilst connected to PC, in the Car, in the cradle, out of the cradle, and not connected to anything. Nothing works.

18 months ago I noticed that when I removed the Tomtom from the cradle in the car it started to turn off immediately, rather than enquire whether to shutdown or cancel shutdown countdown. Becasue of this I think there is something wrong with the battery and it requries replacing.

Anyone have any ideas?

    To add on.....
    When I finally get the power to work with the Tomtom connected to any device (except the PC) it ask me to connect it to the PC.
    It connects to the PC just fine evertime and asks to connect to MyDrive Connect which can be done successfully.

    It just won't work any other time.

    Need some ideas from a TomTom technician.

    Is the battery any good??

    When your connected to your PC & MyDrive Connect you are obviously connected via the GO 500's Micro USB Port so if the device is charging & working like that then the battery seems to be OK

    The Fault must lies in the Mount, the USB cable, the Power adapter or the vehicle's Power socket

    The Previous NAV4 and Latest (NAV5 WiFi) devices are quite power hungry and can go into "Power saving mode" if not supplied with enough power

    When the device is In use they are designed to be always connected to a power supply
    The Tomtom supplied Power Adapter is rated at 5Volts 1.2Amps
    Even after you have recharged the device externally via a mains charger, when in use in the vehicle, they will still require being connected to a Tomtom supplied Power Adapter (Or a proven suitable 3rd party Power adapter)

    (1)... Do NOT attach them to a dashboard USB port in your vehicle as they normally only supply 500mAmp (0.5Amp) and are for data transfer and not supplying power: See... Note (1)... A dashboard USB port can also fool a NAV4 Device into entering 'Updating Mode' and display the 'Connected to your Computer' splash screen
    (2)... Using a NONE Tomtom 3rd party underpowered or a mismatched cigarette lighter charger can cause the device to go into Power Saving Mode: See... Note (1)
    (3)... On the Models with a built-in SIM, the reduction of power to the SIM can cause the dropping of the traffic info

    Note (1)... At an (Undisclosed) percentage of battery discharge, the device will try to save its power requirements by dimming the screen and eventually powers off the device... Devices with a built-in SIM Card may also lose Live Traffic services

    As a test...
    Try using the Tomtom supplied cable and Tomtom supplied Power Adapter

    The Charger Adaptor and USB Cable supplied by Tomtom WILL run and charge the device at the same time

    Many 3rd party Mismatched Charger Adaptors won't run and charge the device at the same time
    See... It's not simply a power thing.....
