    wont charge in the car.

  • Isharryf Dec 15, 2008

    At home it charges fine, but in the car, the green light is on, but does not charge. I found out that if you ben/enforced the tt910 on the windshielddock a little it does switch to charging. But if you let go, it will easily stop charging. I looks like something is wrong with the connecting between the TT910 and the windshielddock.

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.

Won't charge even though Green light is on and connects to computer. Just put a new battery in.


Yes, possibly a cracked pc board if the unit was dropped. But check to make sure that the charging unit's connector is clean as well as the unit to be charged. I had a problem with my wireless phone and a PDA not charging because of dirty contacts. I got to the contacts using a long Q-tip moisten with Isopropyl alcohol and scrubbed them clean. I now do it about twice a year. No problems since then.

Blank screen but green light is on


I have had this on my 910, It turns out that the motherboard needs replacing and after looking on here its quite common.

Its quite esay to replace and perhaps worth changing the battery whilst your in there as well.

Google for instructions or flick through this site.

Response to picture.


Hi again ,

Well it looks like your'e an investigative type of guy and you digging around is getting to the bottom of your problems. I think you are very much on track and narrowing the possibilities and your last sentence brings out down to just 2 possibilities . I think logic is telling you that downloading voices won't cause a charging problem . I agree , voices can cause wierd things to happen software wise and I know this becuase I ahve seen it several times myself. Especially where it makes the screen look damaged. I had a tomtom one V2 here that ended up with a green only screen with black lines down it and that turned out to be a corrupted celebrity voice file. I never found out which voice it was but just deleted all the celebrity voices and hey presto the screen came back to normal.
Anyway , back to your problems. I see no logical connection between downloading voices and a charging issue . The battery charges by physical connection and regulation through electronic components and also becuase it charges the battery even whilst the TomTom is switched off then we can be confident that any software has no influence on battery charging. This tells us that out of the 2 possibilities you have narrowed it down to it must be a "contact" issue. Also because you wasn't aware of the release button you were actually disenguaging the TomTom from it's mount incorrectly. So, to sum up : .... we have .... 1/ cause ..... 2/ symptoms ...... 3/ cure ... = new car mount required.

Well done.


best regards

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

My tomtom go 910 will not switch on it has the green light on at the top left when plugged into a charger but nothing turns on when pressing button for 2 seconds any ideas??


In general I find these sort of problems can be fixed by the below

If the Tomtom loses battery power it might cease to function with a blank screen but will show a green light when you charge it. The trick is charge it on the mains charger for at least two hours. Then reset the device with a paper clip. If you get no reponse hold down the on button for at least 20 secs and the device will show the Tomtom logo and play a drum roll and startup normally.

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.
