Just purchased tomtom v3 Great britan followed updates via tom tom home web site now tells me cannot load map thats been downloaded keeps asking for activation code ? just want to reistall as it was when we purchased it?

1) You need to download and install TomTom Home on your PC/Laptop: see attached official TomTom link:
http://www.tomtom.com/services/service.php?id=16

2) You will then need to connect your GPS unit via the provided USB cable to your PC/Laptop withTomTom Home running and connected to the internet.

3) Your current MAP can then be updated via the 'Update' selection. Any other 'system' files will also be updated automatically using this function.

4) Using TomTom Home, you can also download free add-ons such as 'Voices' and 'Colors schemes'.

If you just bought the unit within 3 months, you can update to the latest Map free of charge using 'Latest Map Guarantee' function in TomTom Home otherwise, there are NO FREE ADDITIONAL FREE MAPS.

Hope it Help: let me know how you go!

That is really strange!
I can only suggest that you verify what MAPs are physically on your TomTom device by connecting it to a PC/LAPTOP and use Windows Explorer to look at your GPS drive folders: should see a folder for each 'country' (like GUAM).
The normal way to check which maps are registred and loaded on your device is to use TomTom Home -> Update maps function: it will show you the status or whereabout of any Maps that you have loaded or backup and which one can be purchased.
Hope it helps: let me know how you go.
ps.i f you wisely backup your device on a regular basis (via TomTom Home or direct copy to your PC/LAPTOP), you could always RESTORE FROM BACKUP and start again.

You will need to Purchase and load required US MAP(s) via 'TOM TOM HOME'.
When the new MAPs are registred to your device, you can then use the 'Change preference' -> manage Maps -> Switch Map -> then select the appropriate 'registred' US MAP.

Please note: always backup your GPS via 'Tom Tom Home' backup utilities first!
If you have limited storage, you may need to delete your existing map(s), that were previously back-up, before loading the US Maps

Use Tom Tom Home.

You'll only get free updates for a certain period after purchase. Beyond that time, you'll need to buy them.

To update maps you should run Tom Tom home on your computer and then connect the GPS

It will then ask you if you want to connect to the computer and you would tell your GPS yes.

Tom Tom home will once it finds your GPS then proceed to do any minor updates.

If your map is out of date it will offer you the option of purchasing a newer version.

don't be tempted to look for free / pirate maps !
These can cause problems in starting up your GPS (believe me)

Tom Tom map prices are not too bad and compared to many GPS are quite easy to install using Tom Tom home.

If you don't have Tom Tom home the latest version can be found here.

Use Tom Tom Home to find new maps and updates.

I would recommend you only do a map upgrade if you definatly need to as looking at other posts on this forum lots of people have problems after trying to update maps.
Updating maps is NOT FREE , you have to pay for updates and after downloading updates you need to reactivate the map with your product code . Only do an update after backing up your existing maps other sie you might have trouble reverting back if the download goes wrong.

GOOD LUCK

Reinstall TomTom Home and you should be able to update the maps. TomTom's customer support is also very helpful and can troubleshoot you through the issue- http://us.support.tomtom.com/cgi-bin/tomtom_us.cfg/php/enduser/std_alp.php

I have managed to solve the problem of loading a new map on my Go700 using a Mac. I discovered that Tomtom is incompatible with the Leopad operaying system, despite the protestations of the idiots at Tomtom ,so I reverted to an older Mac using Tiger.
Taking the instructions given to crinold, I tried to erase the disc on the 700 using home 1.5 - and it didn't work. So I went to disc utilities, highlighted and erased the Tomtom disc, and opened home 2,5. After being refused entry several times, like being told to load an already loaded device, I persevered, and managed, slowly, to add the map I had bought for 78 euros. T]One point oif interes is that when I bought the map, they site stated it would cost 63 pounds sterling, but switched it to euros when the invoice arrived. at a rate very favourable to Tomtom - funny, that.
This is sharp practice,probably illegal in many countries,, but, to be honest, dealing with the mysterious Tomtom company is so frustrating, that I don't have the time or inclination to fight them for the money they cheated from me.
How they survive with such an awful product and extremely bad after sales service is hard to understand - perhaps they won't ... we live in hope.

You have to download TomTom home, plug your device in via a USB device and TomTom home will start up. You can then download and update your files..

Make sure Tom Tom Home has finished updating your device before you unplug it or you will corrupt the device and render it useless..
