20 Most Recent Tomtom ONE GPS Receiver - Page 3 Questions & Answers

Make sure it is charged and when you let it run, make sure you can see the sky. The receiver in the TomTom should have direct contact with at least 5 or 6 satellites. When you are in buildings, or to close to high buildings, it could be the TomTon will notice. Give it about 2 minutes to find its location, when you switch it on in a place where you did not switch it of. It needs more time to find and calculate where it is when you brought is somewhere else after switching off.

Attached is a sequence of photos on how to get to and change the power control chip - the one that is probably damaged. This is for the Tom Tom I repaired and yours could be different however, there will be a power control chip of some kind (check out the part numbers to see which one it is) and it will be this that is damaged and will need replacing. The Power control chip is the hardest to replace as you cannot get to the 'legs' to solder them. To remove the old one, just apply a large soldering iron bit (with a blob of solder on it to make good thermal contact to the top of the chip) and heat up the whole chip until it is free. Lift it off straight away with tweezers. Clean up the solder pads with solder wick and then apply a SMALL amount of solder paste to each pad. It is improtant that this is a SMALL amount and is equal on all pads so the new chip sits square and true when you put it on. Make sure the chip is in the middle of the pad patern and push it into place. Now for the tricky part....either usa a large soldering iron and heat the chip until it melts the solder paste and drops into place or, use a hot air gun with a small nozzle and do the same thing. Great care needs to be taken to ensure you do not heat up the near by parts so the soldering iron is best but you have to remove it as soon as the chip falls into place. The surface tension of the solder should centre the chip up if it is slightly out but you need to get it possitioned as good as you can before you heat it up. Take care not to move the chip as you heat it. You will need a fine bit in the soldering iron for the diode and any other parts you may need.

You should start with TT1 and work through to TT7.

As well as this chip, if the power supply went high (12 volts) then the zener diode on the input to this chip will also have been destroyed - you should see signs of this just by looking at the device (see photo TT6)

The most difficult bits are: -

Opening the connector to the LCD. This can be done by gently lifting up the PCB to see the connector on the back and then pushing up the 2 ends of the connectors white locking bar. Replacement is also very tricky but with care it can be done. As an alternative, you can remove the LCD complete by gently flexing the plastic surround to it and freeing the display from the case. It is then easy to disconnect and re-connect the LCD to the PCB.

Removing the tin cover from the back of the PCB so that you can get to the power control chip. This takes time and a hot soldering iron with good solder wick to remove the solder. Having liberated a couple of lugs you can remove the others by gently lifting the cover near to a lug and heating that lug to pull it through the PCB. Don't burn your fingers though!

The parts are easy to obtain from either Farnell or RS Components - RS have trade counters you can go to and Farnell have a retail side CPC you can find them at http://cpc.farnell.com/. If you have problems let me know and I will see what I can do.

To update your unit you must create an account by supplying a valid email address. I suppose this is akin to a registration.
To effect that you install the Tomtom Home software on your computer. Then you connect the unit to the computer. When it asks you if you want to connect to the computer, tap Yes and the HOME software will open allowing you to update maps etc. You will be asked to create an account.

this problem just happened to me. i'd just bought my new tomtom one and tested it on the journey home. all was well and i was really impressed. that was until I got it home and went to update it to get the latest maps for my area. I installed all the software as instructed by the on screen prompts and downloaded the latest updates. i then went to turn the device on, and was greeted by a message stating ''no maps found!''

after almost two hours of complete frustration, i then tried probably the easiest solution anyone could think of:

First of all, connect the device to your computer and close down tom tom home. (making sure it isn't even open in the system tray).

Now, open my computer and find the device. it will be labelled as a storage device (mine was drive G). Open it up and find where the maps are saved to. Something like, UK and Ireland, or something similar relating the place you live. Once located, delete them manually.

Now, reopen tomtom home and go to tools. Click ''use latest map guarantee''. It will then download the maps again and install them onto the device.

Next disconnect using the option 'disconnect device'' from the device menu.

Finally turn on your tom tom if it doesn't automatically, and you should be back in business. This worked for me, after trying numerous way more complicated solutions I found in various forums.

Hope it works for you too!

yes there is a fuse on the adaptor end
unscrew it and put a new one in.

first of all make sure there is a clear line of sight with the sky ( middle on the bottom of the window) also important make sure the charger connects well. sometimes it needs a long time to find so try fixing satelite position while not moving for example at home near open window while charging

Just buy another GPS, a lot of devices have internal batteries and are not supposed to be changed/replaced, for the effort and the cost of the new battery and screw drivers and the time to pull it apart would be easier just to buy another second hand, plus if anything breaks while trying to fix it your stuffed

so what is the problem?

There should be a slide button or switch somewhere on the rear of the screen if it doesn't light up the screen may need to be recharged.

Before you disconnect the tomtom (device) from your computer, you'll want to remove the device (safely). One way to do it is to select the TomTom device (drive) and (right click to see a drop-down menu) and select "eject". Another way is to click on the "remove device safely" icon, usually at right corner of ( bottom ) band, select the device and click on it to remove it safely. Or are you asking how to remove the (tomtom) files/maps, etc. from your (TomTom) backup folders on your computer ?

TomTom is selling the voices, but I know at least 100 different voices in lots of languages are around on the net. There are even descriptions how to record your won voice, make little files from it and place that as a voice in TomTom. Im affraid it is not legal to send any of the voices TomTom is selling. So you have to Searcy for yourself. If I ever fine a link I will post it.

You might like to try this procedure from the Tom Tom site: Are you able to connect your device to the computer and operate it via TT Home? Please try that and just plan a route in the emulator (operate my device). Afterwards disconnect your device safely using the blue disconnect button in the right bottom corner. If that doesn't help try reinstalling the application on your device.

1. Create a backup of your device. How to create a backup of your device (hyperlink)
2. Open TT Home and go to manage my device -> items on my device -> application -> remove to uninstall the application.
3. Now to reinstall the application please go to update my device and install the application update that should be offered. Install no other updates.
4. Now restart your device.
5. You may have to repeat the last two steps a few times until there are no more application updates pending.
6. If it was succesful please create another backup of the working unit. You may also install the remaining updates now.
