After 14hrs of installing updates inc GPS quick fix nothing is still working, no GPS signal. I have also tried quick reset. So my just over 1yr old sat nav is useless, as it was yesterday whilst I was in the middle of nowhere in rural area with four kids. Thanks TomTom! Any useful suggestions on fixing appreciated

    Have you tried a Soft/Drum roll restart on the device ???? This restarts the devices Operating System afresh


    Charge the device for at least 2Hrs "OR" have the device plugged into a power supply
    Press and hold the on/off button until you hear a drum-roll sound then release the on/off button.
    You won’t lose anything; it’s just like rebooting your PC
    I use a Soft/drum-roll start after any upgrade large or small.
    It’s also useful to keep in mind for sorting out most minor niggles......

    If possible, for the for the first Satellite fix, go outside with a clear view of the Sky

    Thanks. I tried all of that and no effect...I went outside and no gps reception at all detected. I will try again later I guess in case by some miracle it resolves. Soft reset doesn’t seem to do anything so far as I can see... Thanks

    Mine stopped working last Sunday. After hours of updating, I can't get a valid GPS signal!!
    I've reset a number of times but still no signal.
    When I plot a route it asks if I want to start from last known position (which is always where I am). How can it know where I am with no GPS signal??????

    I know this is an old post but getting same problem with a Start 25 that I have not used for a while, tried installing the quickGPSfix which says installed correctly but yet still shows as needs updating, even tried uninstalling, deleting all folders and reinstalling Mydrive and installed it on another computer, done soft resets and drum roll etc but still the same, anyone found a solution for the gps fix yet ?
    Also done a full reset of Start 25 to default which also made no difference.

    Welcome to the site....
    Is the latest NAV3 Operating system installed on the Start 25 ???
    Release date: 26-Jul-18
    Version: 12.075
    Bug fixes and improvements: Various performance improvements and bug fixes have been implemented.
    This update prepares your navigation device for the week number rollover in April 2019 which has an impact on GPS.

    A Drum-roll Soft Start can help.... Hold the ON/OFF Power button in until you hear a Drum-roll sound... Then release the button.... This will reinitialize the device's Operating System, like restarting your PC

    Method: Fully charge the Battery (At least 2 Hours)
    (Preferably using something like a Smartphone Charger + Using the Tomtom USB lead)
    A low battery can cause GPS Satellite fix problems...
    First Plan a route on the device... Now place the device outside with a clear view to the sky
    (I used a 5200 mAh battery power-pack... while waiting for a Satellite lock)
    It can take anything up to 30 Minutes to get the first Satellite Lock
    After the Initial 'First Lock' the device should lock quickly onto the Satellites

    If you are still struggling to get a GPS Fix
    I have found with my Car parked on the drive, if I placed the device on the centre of the Car's roof (I used one of those 'Sticky' rubber mats to stop it sliding off the roof)
    The device will obtain it's first GPS Satellite lock more quickly... The metal roof of the Car acts as a ground-plane for the SatNav GPS Antenna and increases the signal strength

    Test... GO 825 Live connected to a 5200 mAh battery power-pack... PND Displaying 'GPS Status Menu'
    (1)... Centre of Car roof (Parked on drive)
    Signal strength 86% Connected Satellites 9
    (2)... Outside clear view to the sky....
    Signal strength 61% Connected Satellites 6
    (3)... Indoors 1st floor one metre from window....
    Signal strength 51% Connected Satellites 4
    (4)... Indoors ground floor one metre from window....
    Signal strength 41% Connected Satellites 3
