Hi, Tom Tom 710 has not come on for weeks.

I guess that you have already made sure the battery is charged enough to power the Sat Nav.... In the back of the Tom Tom where the cradle attaches, there is a tiny hole at the top where you can insert a small object such as a sewing needle in order to press the reset button; However, you may find that like mine the hole doesn't line-up with the button and therefore you can't reset the unit unless you remove the casing. if this is the case it's best to search You Tube and watch the short video as to what exactly to do! (it's really not hard)

Hope this helps

the go 710 has a reset under the mount (see picture below) charge it up for a few hours, then get yourself a small paperclip and depress the rest for 15- 20 seconds.if it doesnt power up, press and hold the power button for up to 10 seconds.

if you need more help, just post back.

if it does not proceed when the icon is selected, presume data corruption or in fact no data.
TomTom is renouned for this type of problem.
try rteinstalling the map data from the source.

try a reset first ( small pinhole on rear) put open paperclip end in and gently push the button inside) if this still fails then data installation is the go

TomTom say that you will need to return the unit to them to unlock it, but there is an independant prog download available that costs £40. How good that is I don't know, so I suggest you mail TomTom Service dept to see what they say. I reckon it is the cheapest alternative.

What I can suggest is download the drivers & software first .. Than buy another brand of memory card.. I had same issue with a Mp3 player that I had purchased.. It wouldnt recognise the card even though it was setup properly.. I returned it and baught a different brand.. Worked Like a Charm..

#2 If you for some reason cant get the software to install or work properly, I suggest you buy a new Tom Tom (( EXACT MODEL )) and than take the old Tom Tom put it in the new box and take it back with your receipt and tell them this doesnt work.. Ive done that b4 with a Speaker system and it wasnt an issue with the store...

Good Luck !

not sure but try an other device on the car plug to see if it works??????????? could be the plug.

Please try a reset:

Hi, i did the same thing with my tom tom 300 go, i fixed it by borrowing my mothers sd card from her tom tom 710, i put the card into a card reader and copied the hole card to my computer then copied it back onto my sd card out of my tomtom then put in mine and bingo it worked with all the fetchers that her tom tom had and the updated maps it still said it was a 300 but had the 710 stuff try this it worked for me it should work for you.

leave on charge for two hours, then with the SD card out hold down the reset button at the back of unit for ten seconds and then the 'on' switch for ten seconds.

1. Activate the TeleType GPS program

2. Select Tools>GPS Status>Status.

3. Look closely at the GPS output that is displayed in the View Status menu. Data should be flowing even when the GPS receiver has not locked in the position.

The data string that begins:
GPGSV... is "bad data" because the receiver has not locked into the satellites.

Whereas:
GPGSA... is "good data" indicating that the receiver has locked into the satellites. Remember - "A-Okay"

4. Once the data is flowing, go outside away from buildings, select the Satellites tab (Tools>GPS Status>Satellites), and watch the satellite signal strength
