TomTom locks up once a route is calculated

Go Live 1005 finds GPS signal and tracks position perfectly. When a destination is entered it calculates the route indicating distance and time, however when you confirm ('done' button) it locks up and the screen alternates from blank to the start up screen. Eventually, anything from 5 to 45 mins, the screen indicates no valid GPS signal. This only stared to happen following the April GPS update. I've tried resetting several times and the same thing always happens. Has anyone got any ideas??

    Hi
    @Kuga

    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 say 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)
    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.....

    (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) & (2)

    (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 (3)

    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
    Note (2)... A dashboard USB port can also fool a NAV4 Device into entering 'Updating Mode' and display the Connected to your Computer splash screen
    Note (3)... I tried connecting my Tomtom GO 6200 to my Cars USB port, checked the connection status it reports 'Connected over USB' --> 'GPRS (SIM) Disconnected'

    After reading most of the posting in the thread, I'm going to try down loading a smaller map as this seems to have worked for most users. Fingers crossed!!

    Zone 4 map installed and so far seems to be working as it should.
    Thanks to everyone for their input.
