I have a TomTom 910. I accidentally used the wrong car powercable and there was a puff of smoke......... burning smell. On the docking unit the green light comes on but that is all. Dead or alive?

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'm presuming that it use to turn on,yes? try doing a soft reset by removing it from the dock and turning it over and removing the sd card (if you have one installed), and then, using a straightened paper clip or straight pin, locate the reset hole (about 1" to the left of the sd card slot) and push it for about 15 seconds. Hopefully after that you will be able to turn the unit on. If that doesn't work, you'll have to call tech support.
start tomtom home if it does not start automaticlly when you turn on your tomtom and connect it to your computer..if you dont have tomtom home, you can get it HERE.
if its still not connecting try another usb cable although im not sure in that one disconnects from the home dock on the 910
( i assume your using the home dock because thats the only way a 910 will hook up to a computer)
Yes Chris it can be repaired. I do it all the time. The culprit is usually the negative pin. The negative pin is the gold pin on the far right hand side. With the unit upside down (you can see the contact pins on the board) and the lcd faceing you the negative pin will be on your far right hand side just below the reset hole. Doing it and telling you how to do it are two different matters.
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.
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.
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 )
I dont think so. The unit runs on 5 volts (why I dont know!!!) so the first thing to fry on a 12v hit is the on-off switch then some of the components. Sorry
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
