American maps if i download the western american map to my tomtom will i a) have enough memory b) able to get back the original maps afterwards

Hi there, download map of Italy to a memory card, as I have done. Malta & Gozo are there.
At last I can travel around Malta without getting lost!

Yes you can I have europe and canada on mine.

just plug your tomtom into your computer and start tomtom home

On the computer screen for tomtom select ADD MAPS

Here you can select and buy the maps you need.

Once you have confirmed the purchase you will be given instructions on how to download etc

Some maps may take a little time to install to the tomtom itself.

you should also ensure there is enough space on your tomtom
If not you will have to get an SD memory card.

I use a 4gb one that still has lots of room to spare

you may have run out of memory for the full map, your device can use a 2Gb max SDcard which should be enough for all your maps. It will have put placeholder there and tryed to drop the full map but you can only see the bit it could store to the memory.

First make sure you have a backup of your NEW ONE XL. You should be able to connect your XL to your PC using USB but not use TomTom home software. Your TomTom should appear in "my computer" as a drive . OR , put the SD card in a USB reader connected to a PC , that way you can look at and copy from or to the SD card.
You should be able to copy the map you have to the SD card directly ( if there is enough room on it ) , if theres not enough room , get a new bigger card , copy all the backup files you already have on your PC + the map you want. You might / should be then able to activate that map in the XL using the codes you say you have for the maps. if you try to do this using TomTom home it might have some restiction to stop you activating the required map but hopefully you should be able to do it manually as described above rather than use TomTom home. ... GOOD LUCK .

Please rate this reply if you find it useful .

You can back up all your current maps and install North American maps for Florida using TomTom Home. You can switch back to European maps when you get back to the UK as well- I used my TomTom Home to manage my GPS and I find it can be very useful in situations like that

Can you tell me . After you installed the Western Europe map , did you at any time activate it ? ie , did you have to enter an authorisation code ?

If you have TomTom that have the slot for SD card, then it should accepted the SD card. The instruction for how to use the SD card is simple, but it is hidden in the TomTom Home, that's why it's difficult to find it. Below are the instruction how to use the SD card.

1. Format the SD card (FAT32) and do not stick the SD in the slot yet
2. Run Backup (connect TomTom device to computer)
3. Disconnect TomTom from computer and turn off
4. Slide the SD into the slot and connect TomTom back to computer (choose "yes")
5. In the TomTom Home menu, Choosen Backup & Restore >>> and choosen Restore

TomTom Home will add all applications to the SD card. So the internal memory still have the applications and the SD card also had the same applications. Everytime you slide the card in, TomTom will automatic detect and use it as its primary storage, if it not detect, you can go to the device menu and pick the device to connect to.
Whenver you take the SD card out, then TomTom will use its internal memory.

Hope this helpful

Its more than likely that your NEW SD card is faulty. First thing i suggest is you try another card. Then recopy everything off your old card and then recopy the western erope map also.

You could probably just manually delete the Canada/USA maps from the device, and copy over the europe (or whichever ones you need) to the device. 
Just plug it in, and view the memory like a normal usb drive..delete the old, copy over the new.
Don't forget to use tomtom home to backup your gps device to your computer first (thus saving your canada maps for later..)
Afterwards, you would probably have to go into your preferences and choose the europe maps.
Good luck!
