Tom Tom Go 520 Wont connect via USB

Technician,s job.

i dont think the iphone will pair with the tom tom gps, because they use a different satellite & interface....iphone is running on Google whereas tom tom has its own satellite.

I had the same problem with a 750.
I cured it (accidentally I must add) by inserting a memory card.
I guess the last time I connected and disconnected the 750 it had a memory card in and without one inserted it would not recognise the device.
Strange reason but worked for me.

Check your cable from your tom tom to your phone.

you have to use atleast windows xp sp2 and the drivers will load automatically. you can also use windows vista or a mac (not sure of version for macs) if you are using one of those operating systems and still can get your tomtom to hook up, try a different usb slot. reboot your pc if your sure you have met the os requirement.bill

Hi canal_boat_m

Try this solution:

STEP 1 Un-install Tom Tom Home from your PC

STEP 2 Click on the link below:

http://tomtom.com/lib/img/cs/S4S/files/RemoveRegEntries_TTGOv1.exe
This will download a little removal program for the Tom Tom Home program.
A Black window will appear briefly then close.
• Make sure that you have got Administrator rights on the PC. Otherwise you may not be allowed to connect new hardware (especially the case when using office computers)
• Reboot your PC

STEP 3 Visit Tom Tom website and download the current new version of Tom Tom Home and install it to your PC
STEP 4 Connect the TomTom

• Make sure the device is fully charged before connecting it to the computer. Ideally a mininum of 4 hours charge.
• Reset the device using a paper clip (see http://www.tomtom.com/6965). When resetting, keep the reset button pushed in for at least 20 seconds, but DO NOT turn the device back on just yet.
• Ensure that your TomTom has power connected to it. There should be a green light on the TomTom unit. If your device came with a Home Charger, please make sure that is plugged in to the TomTom also.
Your Tom Tom should ask you to 'Connect to Computer' if it does tap YES.

SOLUTION:
Your unit should now be recognized by your PC.

IF IT DOESN'T then follow the instructions below:

1. Connect your unit to your PC;
2. Copy two folders to your PC (namely 'Raster' and the one which holds all your maps - probably called 'United Kingdom and Eire';
3. Using Windows Utility, right click on the Tom Tom drive unit and select Fomat;
4. Switch off the unit and soft-reset it with a paper clip (but hold it in for at least 20 mins) and then re-connect it and power it up;
5. Tom Tom Home should now detect the unit and your unit should ask you to 'Connect to Computer' so tap YES;
6. Tom Tom Home will now say your device needs updating - and if you apply all the changes it will restore it to Factory Finished!
7. Then all's needed is to replace the two folders you backed up and any other items like mp3's and sounds, pics, etc.

Hold the reset button until you see it start up again. If this does not work plug it into a power source via USB and then do another reset.

Hi all,
I got the following response to this little problem. Will try it out and hopefully my 520 will work again soon.

To ensure that your device is correctly connected to your PC, please do the following:-

STEP 1 Run the Registry Cleaner Tool

• Disconnect the TomTom and remove any USB devices from your PC, If you use a USB Hub, please disconnect that also.
• Run the RemoveRegEntries tool. You can download it from :-http://tomtom.com/lib/img/cs/S4S/files/RemoveRegEntries_TTGOv1.exe
A Black window will appear briefly then close.
• Make sure that you have got Administrator rights on the PC. Otherwise you may not be allowed to connect new hardware (especially the case when using office computers)
• Reboot your PC

STEP 2 Connect the TomTom

• Make sure the device is fully charged before connecting it to the computer. Ideally a mininum of 4 hours charge.
• Reset the device using a paper clip (see http://www.tomtom.com/6965). When resetting, keep the reset button pushed in for at least 20 seconds, but DO NOT turn the device back on just yet.
• Ensure that your TomTom has power connected to it. There should be a green light on the TomTom unit. If your device came with a Home Charger, please make sure that is plugged in to the TomTom also.
• Connect the TomTom to a USB port on the back of your PC. We strongly suggest that you use a USB 2.0 port and not a USB 1.1 Port. (USB 2.0 ports are faster USB ports, which are standard on all modern PC's, older PC's and some laptops may still use USB 1.1 ports which are slower and can prevent some USB devices from connecting properly).

STEP 3 Switch the TomTom On.

• On your PC, open My Computer
• Now switch the TomTom On while it is connected to the PC with the green light on.
• Look at My Computer, do any disk drives appear as you switch the TomTom On? If so, which drive letter is it?
• Double click on the TomTom disk.
• What files and yellow folders do you see?, please make a note of them and reply back with what files and yellow folders you see. If possible, please provide us with a screenshot showing all the details.

If the device is NOT listed as a 'Removable drive' under 'My Computer' when you switch the TomTom On, try the following:-

STEP 4 Check Device Manager

• Disconnect the TomTom from the computer.
• It is likely that you have a Firewall on your PC, in some cases, Firewalls can prevent USB devices from being recognized by the PC. We suggest configuring your Firewall and security settings to allow all USB devices to connect to your PC. Once you have done this, we suggest trying the steps above again.
• Go to 'Start' and right-click on 'My Computer' and select 'Properties'
• Select the 'Hardware' tab
• Expand 'Disk drives'. If the TomTom device is shown there with a red cross, right-click on it and select 'Enable'
• Check under 'My Computer' to see if the device now shows up as a 'Removable drive'.

We also suggest it is a good idea to try to connect your TomTom to another PC to see if you get the same problem.

This may be a simple case of removing all the entire active sync directory. If you used to connect via serial+com it wont be detected on usb. Remove active sync from your pc via the add remove program feture, then reboot and re install. Then run the make a connection again from active sync. Hope this helps
