Top 20 Tomtom GO 910 Questions & Answers

Tomtoms store data in a non volatile format, either to an SD card, Flash memory or to a hard drive, none of the above require a battery backup. If the battery is removed the only data that should be lost is the time and date

You can't because tom tom links the user name to the GPS unit so you should contact the previous owner.

There is no real manual for this, I have done it before though and have typed out the directions here for you, plus a link for the new battery if you need it:

Please make sure you rate my answer 4 thumbs up, it is extremely important to me. I would be forever grateful if you could do so. If you need more help on this question please just respond to my answer here and I will get right back to you.

New Battery:

1) Remove 4 screws under ends of rubber strips on back. (All screws are Torx number 6)

2) Remove back cover. Front frame around screen comes off easier now.

3) Remove 2 screws in round top circuit board. Remove 4 screws from lower circuit board. These two boards may have a glue connection. Do not worry if it separates

4) Lay back circuit boards to unplug battery. Note flat ribbon cables are fragile. The 3 wire plug is the battery. Unplug wires to battery from receptacle on circuit board.

5) Remove front screen by pressing a screwdriver against the small metal tags that follow the edge of the screen. The tabs need to be pushed in slightly to allow you to lift the screen out. It may need some leverage, but be careful not to put the screwdriver to far behind the screen as there are a couple of thin cables for the connections.

6) To remove the hard drive you may need to unscrew the vertical black tags about 2 cm long. These simply come away and are grasping the business card size silver box IE the hard drive. The rubber end caps are pressed in, pry out with small screw driver.
7) Remove battery and replace. Note the two sided sticky tape around battery. When putting more tape on, be careful you do not put to much around the right hand end as it will connect with the thin cable when you put it all back together.

9) Reverse assembly. Mine works fine now, good luck. (and so does mine! BLP)
Footnotes: I did not have a Torx #6 screwdriver nor could I buy one locally. I found a #7 mini star bit works just fine. Source: Harbor Freight item # 93316, 6 piece Mini Star Bit Set - $3 PMVN - 9/19/2009
I am not advertising but Batteryship.com included with the battery #5 & #6 torx screwdrivers, a very small philips (star), a straight screwdriver and a plastic pry tool. Whatever I paid more than another place it was worth it.

When disassembling do not remove the battery clip. Just pop out the battery from the front (experienced having to reassemble that whole thing). Also having a set of tweezers to put the electrical connections back together helped a bunch.

Backup the Tomtom to your computer. !!!!!!!!
Format the Tomtom hard disk
Logon to Tomtom home and carry out an update
When it has completely finished updating copy the map directory back onto the root of your Tomtom hard disk.

This action forces the Tomtom home site to completely update the program on your Tomtom to the latest applicable application.
This may involve updating the the bootloader as well as the Navcore software.
The maps will go straight back on ok as they should already have been initialised for that device.

Most new Navcores now incorporate the Quickfix which enables the sattelite signal to lock on quicker.
Regular visits to the Tomtom home website will update the quickfix data which really needs to be done weekly as the data expires.

Pressing the reset button also renders the old Quickfix data useless.

If the above does not work then I suggest that you have a hardware problem which would require a professional repair.

go to the support site here and download the manual

Two possibilities:
- if someone has used the wrong charger, and connected it to a 12V supply, the mainboard may be damaged. In that case, you need a replacement.
- the battery may be discharged. Even if the green light is on, it doesn't necessarily charge up. Try pushing it hard onto the mount for a few minutes, then see if it will turn on.

I think it is the same dock contact problem.
the battery won't charge and can't supply enough
power for harddrive to rotate and it shutdown by itself.

If your device is not starting up properly, follow the steps below:

1. Soft reset your device.
   
   
2. If your device still does not start up, then reinstall the TomTom application using HOME.

you need to choose a computer voice instead of a human voice. go to change preference->voice...
in the voice selection menu, it will tell you this voice is computer male or human female, make sure you pick a computer one, then it will read the street name

Go to link below to see how to reset.

Power on the TT 910 and then press the Reset Button on the base of the TT. It is a tiny hole with a hidden button. use a rounded object, match end or soft pencil to puch the button. Then reconnect it to the PC and the PC will see the TT. Note that you may have to reload apps and maps depending on the state of the TT.

Had exactly the same scenario. Must be a production flaw that L2 sticks to the GPS piggypacked board.
Looked into another TT and found a 100 (µH assumed) on the same spot for this backlight P/S. Took an old Vodaphone/Arcor DSL Modem apart and found three coils 101, 2R2 and 100 ......
The 100 is working fine - had to shift it aside by some jumper wires.
Light is on again.

suggest reload tom tom software on to memory card but format card before doing so

It is very small - a pinhole. Use a paperclip to press the button which is sunk inside the small hole.

Hopefully all you need to do is a soft reset. To do this use a streightened paper clip and insert it into the small round hole marked reset on the bottom of your tt. Gently press the reset button in until you feel a click. Hold the reset button in for 20 seconds. Hope this does the job.

Heres a link. Hope it helps. I can't read chineese!!!!!!
