Map Update When I tried to update my maps through TomTom Home, the device says Cannot Update Memory Full. Sorry and I can do nothing. How can I update the maps? It is supposed to have Lifetime updates. The place where I bought the device told me to purchase a memory card - however there is no slot fro a memory card.

To take advantage of mapshare, your maps must be version 6.75 or higher, and software version 7.xxx
You can also buy new maps.

In both cases, you will have to use the software TomTom Home.

The best thing to do is up grade your SD card to a 2 gig this will give you plenty of space, for maps and up grades.Graham

I am assuming that, without being a GEEK, you are sufficiently proficient with a computer. I will describe the procedure with all the necessary details. I use Windows XP and all folders I refer to are in Windows OS hierarchy. I have tried all except starting from the SD card, I happen not to have a 2GB card ready.
I suggest you read the whole post, think about its feasability from your point of view, and proceed from there. If you have any misgivings about what I say, DO NOT DO IT. I shall NOT BE HELD RESPONSIBLE FOR ANY DAMAGE TO YOUR GPS.

First of all you should install the HOME application on your computer. Then you connect your GPS to the computer. When it asks you if you want to connect to the computer tap YES, and the HOME application will launch. You may let it perform an update (if any ) of the OS (application that manages the GPS). Do not let it make any update of the OLD map. On each screen you have a CANCEL button.

Use the TomTom Home Application to backup your device. The backup will be stored on your computer, and you will be able to restore it in case of a problems.

Disconnect your GPS and insert the SD Card in slot. Then connect the GPS to the computer and let it communicate with the HOME application.
When HOME launches it will show you the internal memory of the GPS and the SD card and you are asked to select from where to run the device. Select the external SD card.

If any thing goes wrong STOP.

In the main window of the HOME application use the right arrow to go to go to Backup and restore icon. Click the icon, HOME will restore the application and the old map, all that is on the internal memory.

If that does not work, I think you should copy the content of the backup folder \My Documents\TomTom\HOME\Backup\GO\Backup01 on the SD card. and try restarting the system from the external card.

What remains to be done is to look for the new map and put at the right place in the HOME folder.
Here I will show you the directory hierarchy in WindowsXP
On my computer the map is
\My Documents\TomTom\HOME\Download\complete\map
In this directory there is folder called North_America_2GB. It contains a 1kB activation Zip archive file, a 1.5GB map zip archive, a 6kB table of contents (. toc file) and two image files.

Once the application and the map are on the external SD card you should be able to start the device from the internal memory or the SD card. When you turn it on you will probably see two icons (one of the internal mempory and the other for the SD card) . They will be flashing for a short while. You have to tap the one that you want to start with.

you should download a new one, for your region, to change it and put in the navigator. and, for the future, every time before you make some changes, save all the content in one folder on your pc.
