20 Most Recent 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

My Tomtom 910 is having charging issues.

Hi Evan,

The rubber bungs often come out but it doesnt usually effect the charging although the rubber bung is there to help reduce vibration when used with a mount in a car. I have had many 910's here in the past with the bungs missing but never had any problem with them latching into the mount. I would think your problem is either some other plastic part is worn or broken. However , if you feel that the problem is the bung then I would go with your instinct but you might have to find something else to fit in the hole as parts are not readly available for TomToms unless you buy a whole unit thats faulty to use as parts / spares. Im'e sure something could be made to fit possibly part of an eraser or similar rubber part. You might also be able to use a small rubber cable grommet or similar.
As far as I know , it isnt possible to get a virus on to the TomTom as such but it is possible to get corrupted data on the hard drive ( or SD card with other models ) especially if you download things such as voices etc. I have had TomToms here were owner has downloaded comic voices and the files have caused very strange things to happen with the TomTom. I even had one where a voice file was making it look like the screen was damaged , so , your'e correct in thinking that way. In your case though , I doubt if the dowloaded voices have effected the charging , its more likely the poorly fitting mount thats casuing your problems.
If you manage to get the green light on ( this only shows power is going to the TomTom , it does NOT confirm charging ) then leave it for a few hourse before attempting to turn the TomTom on as that will ensure a resonable amount of charge especially if you battery is very flat.

Hope this helps . ( please rate the above reply if you think its helpful in any way )

Good Luck

Need L2 inductor spec on TomTom GO 910

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.

I just bought a tom

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

Battery indictes low and turns off

I replaced the battery on my TomTom 910 and still no improvement so eventually sprayed the contacts with switch cleaner. Now, no problem. Probably didn't need to replace the battery.

If you unit is outside guarantee then this is worth trying. Might be as well to detach the battery and all other power supplies until the switch cleaner has dried.

Another possible problem is the rubber gromit which forces the contacts to make contact. You could replace this with a bit of rubber from a pencil.

Hope this helps you.

How do you get inside the tomtom 910 to change the

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.

My 910 won't pick up a GPS signal - any

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.

TomTom GO 910 won't turn on.

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.

TomTom Go 920 fails to connect to Sony Ericsson C902 for internet connection

I phoned tomtom help line, they sent me a download by email which i ran on the tomtom which wipes the flash memory clean. Then did a download of latest tomtom operating system form tomtom Home software. When i tried to setup wireless data connection i couldnt believe how quick and easy it done it and now works amazing fast to find traffic updates in secs !! They told me that if you have used the tomtom with a few phones and changed a lot of settings the flash memory gets full and thats what made it stuggle to connect and was slow. Im so pleased it was driving me mad !! Hope you resolve urs the same. The number is 08451610009 Darren.
