My TomTom GO 630 is frozen on locating a GPS signal. How do I reset

Have you tried to shut it down and restart it ?
Or do a "reset", using a "pin" (e.g. paper clip) to insert into the "Reset" hole at the bottom of the unit ? Then start it up again.

default password for pairing any phone with tomtom go 630 is 0000. some phones require you type the password and some do not.

Lots of folks having this problem with differernt model TomToms. It's the USB on the TomTom.

You'll need to "reset" the unit, using a paperclip or narrow pen, hold the reset button in for about 5 seconds and you should be good to go. On the 630 it's on the bottm, right next to the USB port.

Hope this helps!

Solution for No GPS Signal

To pinpoint your location, you need to get signals from at least 4 satellites. If you receive signals from less than 4 satellites or the signals are not strong enough, the Driving View stays gray and one of the following messages is shown in the bottom right corner of the Driving View:

• Waiting for a valid GPS signal
• The GPS signal was lost sec ago

Note: In previous versions of the TomTom application the message may vary.
If you see any of these messages, try the following:

Finding a GPS signal
In the following cases it can take up to 5 minutes to find your current position:

• You use your TomTom device for the first time.
• You haven't used your TomTom device for a longer time.
• Your TomTom device has been relocated without using it (e.g. after traveling by plane or train).

If it takes longer than 5 minutes, make sure that you are in an open place without tall buildings or trees around you.
Once your TomTom device has located your current position, the Driving View is shown in full color and shows your position on the map.
Tip: Most TomTom devices can use QuickGPSfix™ to locate your current position faster.

Flight mode
On devices with built-in GPRS connectivity, flight mode also disables your device’s GPS reception.
To switch flight mode off, tap Flight mode in the preferences menu and then select Restore connections.


Clear View
Your TomTom device must be outdoors to locate your current position.
Try repositioning your device in your car; ideally, try to position it at the lowest possible point directly on the windscreen.
Some vehicles have a heat reflective shield embedded in the windscreen, which may prevent your device from locating your current position. If this is the case in your vehicle, use the TomTom External Antenna Kit (available as an accessory).
Tip: As a reference, place your device outside your parked car to see if it can find your current position.

Do a soft reset by holding the power button down for 15 seconds. then power on and off. it should work. It did for me. if not, call tomtom. they are willing to help quickly

can you locate the reset button and try that first.
