I didn't see a response from my last note, and will be signing off soon (I'm in the USA & its very late), but I wanted to give you the steps to find the model of your device and THEN get the correct software onto your computer - to be able to update the device.
NOTE: That software will be EITHER "TomTom HOME" or "MyDrive Connect' - depending on what model device you have.
The basic steps are:
1) Find the model of your device. Using the first few characters of your serial number can tell you the model of the device, using the following TomTom webpage (click the link).
2) Once you know the model, you can download the correct program - for updating that device. Again, that will be either TomTom HOME or MyDrive Connect.
Once you are on the above page, there SHOULD be links to how to install one of the above programs, AND how to use it to update your device software and/or maps. If you do not see those links, try the FAQS link - at the top of that page.
3) Once you have the correct program installed on your computer, you will run that program, connect the device when instructed, and then follow the prompts on the computer screen.
That's really all there is to it.
Please let me know if you have any trouble at all, and I will respond as quickly as I can (when I get back online).
If this has answered your question(s), please take a moment to rate MY service level (Excellent is my goal) so that I get credit for helping you with this question.
You should see some "stars" to do that, but please let me know if you do NOT see them (you may have to scroll UP or DOWN) or can not use them.
Thanks, ***** *****
