Question about Tomtom GO 910

7 Answers

My Tomtom 910 is having charging issues.

Hi, my name is Evan. I have a go 910 and the little rubber thing on the back fell out and I lost it do you know where I can find one of those. When I go to charge it wont charge properly and unless I push down on the unit on the charger? I think it might because of the missing rubber thing. It's real loose and doesn't stay together. when u pick up the unit. I just bought a new charger hoping that would be the problem but it's not.

The green light comes on. I did the reset thing with paperclip on the back. It will come on for a split second but shut off because of a low battery. Is it possible to get viruses on these things? I don't know if this was a coincidence or not, but I download some free voices off of and that's when it seemed to start not charging properly.

If you have any suggestions that would help.

Thanks Evan

    Thanks for your input. I charged it overnight as soon as I bought a new charger. It didn't charge unless I put pressure on the unit the mount. There must be something loose inside the Tomtom connection that connects to the mount. Maybe the two fans on the back that lock the tomtom to the mount are worn out or something with thenmetal plate. would cleaning the connections with Alchohol make a difference?
    Thanks Evan

    my tom tom 510 is having charging issues it is not charging even know the green light is on , it will only charge when i press down on it

    I have the exact same problem to a T. My guess is it comes from taking it off the car mount incorrectly (blaming the wife). I'm hoping someone posts the correct way to resolve. Ship to TomTom maybe?

    My Tomtom doesn't charge . Light comes on momentarily if you apply pressure on connection (in car as well as on direct charging at home). It seems as if the connection is loose or that the battery is dead.
    Many thanks

I have a Go 510 from 2006 which has the same form factor as the 710 and 910. Mine stopped charging 2 years ago. It was out of warranty so I took it apart and replaced the battery. It worked fine until the new battery drained. Recently, I took it apart again and inspected the contact strip which is mounted to the bottom of the motherboard. I determined it was just a compression fit by carefully prying with a fine screwdriver. I pulled it off and found carbon deposits between the contact strip and the motherboard. I lightly sanded the contact areas and then reassembled. It charges fine now. Today I called TomTom to get a replacement rubber docking enabler but they no longer have them. I made one from an ear plug; it works better than the original rubber docking enabler.

    In addition, I used a 0.0050" drill bit with dremel and drilled into the mounted contact strip. I then screwed eyeglass screws into the drilled holes to make the connection tight. I should have included that.

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

    I think cleaning the contacts might help but you will need to eb careful not to bend them or move them out of position.

    Looking at your TomTom underneath where the mount fits you should see 2 small plastic lugs sticking out at each end of the connector . One at the round external antenna connection and one at the other end. Also at the front of the slot ( towards front of TomTom ) you should see 2 further plastic lugs and these should move out towards the sides of the TomTom when the release button is pressed on the front. If any of these parts are worn or broken then the TomTom won't lock into position. I have taken a photograph shown below ( incidentally this one locks on the mount OK even though it has the rubber bung missing ) so you can check your against this one to see if your plastic lugs look the same .

I have a 910 go too found that where the connection meets from the charger to the tom tom the connection inside the tom tom has broken off from the board slightly. found the same problem wont charge and will only turn on with applied pressure to the charge dock. i took mine apart cause it was pissing me off, and that is when i found that the solder contact was broken from the tom tom hanging from my windshield and bouncing around from bumps and it ended up breaking the contacts on the board for the charging hook up.

Hey, i am having the same kinda problem with my (new) GO 910. I gave the device to a friend and i think he undocked it the wrong way, the green light is burning but it will not charge. It only chagres if i hold it wit the dock in my and and force it a little to the right in the dock. I see that when i go to the status window where you can also see the state of the battery and a summary of your route. then it say "charging" under that little battery icon. I really don't liked the dockkingstation from the beginning. I was thinking it looked to fragille. and now it hhas serious problems... My question is, if this is the weakest part of the whole GO 910... I also ad problems with the HD because it froze the very first time i docked it to thhe computer, i was able to fix that by having the GO 910 do a CHKDSK /F

I personally feel the TomTom GO 910 is a bad thing to have

Posted on Sep 22, 2008

On the windscreen mount there is a charging point. Inside that point should be a gold looking pin. I bet it has broken off.

The fault is the rubber bung or as Tomtom call it "Rubber Docking Enabler". This little rubber bit ensures a good connection between the mount and the 910 thus ensuring charging whilst connected. this extract was taken from someone elses contact with Tomtom customer services on the same subject:

("We apologize for our previous miscommunication. In fact, we do have these "rubber docking enablers" available and can provide you with a replacement. This miscommunication was caused by an internal misunderstanding, for which we apologize.

Two "rubber docking enablers" are on their way to you today. Please let us know if we can be of any further assistance.

With Best Regards

Power to same, but not turning on, can't locate so-called "reset" button on bottom????

Looking at the docking area note the gold connection terminals and which end the round coaxial connector is at. You should also be able to see the green circuit board that the terminals are mounted to. Then next to that you'll see a section of the plastic casing that has a little rubber piece in it. At the end of that part of the case opposite the coaxial connector mentioned earlier you should see a small notch in the plastic. That is the reset button. With the unit on use a regular size paper clip and gently press it in and you unit should reboot.

TomTom910 not charging

This is a common problem with the 910. Try putting an obstacle in the way of the wire to keep it on. Better still is to not use the home dock at all. Just plug the home charger in to the windscreen mount (device connected of course!) and charge it that way. You get a better charge and it will stay on.

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

Thanks for the input.

hi, Check the photo below to see if your plastic lugs are in good condition . If they look OK then it is possible you have a bad contact to the pins or maybe even a bent pin. be careful though as the contacts are very easily damaged if you go prodding around.

stevi at the back of your tom tom where your windscreen dock goes there is a small rubber bumper if you look to the right and down you will see the reset button it is a small hole above the dock socket. sandy

Will not power up

Had same problem with my GO910 unit, after it was about 6 months old. Contacted TomTom and sent unit back. They said that they are aware of the problem. They sent me back a new GO 720 with 2008 maps as they said they could not fix the problem in the 910. and they were not importing anymore 910 into Australia.
