I am in Australia, have used tomtom xl first time last week. I am going to USA in 7 days does it have usa maps in it, if not where do I download them from.

plug into a comp that is online and go to tomtom site to find out

It is a good thing that TomTom more or less functions like a computer. Start with downloading the TomTom home from TomTom website.
Then follow the link below.

Then comes the tricky part. If you are in US or Canada, you will see that the new map will not install properly. Reason? not enough space in your Tom Tom for 2 maps simultaneously.
Solution : Connect the GPS to computer via USB cable . copy every thing to a folder in your computer. Make a second copy as a precautionary method. Now go back to the GPS (drive) in the file manger. (delete the maps-USA-Canad-Mexico folder. This is an example, if you are from a different country find the map folder and delete it. ) You will see that you have freed approximately 1.6 GB space. Go back to TOMTOM home and use the latest map guarantee feature. This time around you will see that the map updates completes without failure.
Check it out by driving around through some roads you know.
Good luck

Puerto Rico is included with the latest 'USA' or 'USA & CANADA' or 'USA & Mexico' TomTom maps.
Depending on what map came originally with your unit, you can download the required USA map either for free or for a fee via 'TomTom Home' while connected to the internet. Alternatively, you can get it from a retail shop or from Tomtom directly on a DVD. It is a new Map, it will need to be registred to your device: you cannot just simply copy the maps from somebody else ...
WARNING: unless your unit came with a SD memory slot or came with 1GB of internal memory, YOU WILL NOT BE ABLE TO USE those rather large maps! For instance, Tomtom One V3 in Australia only come with 512K and NO SD memory slot!
Hope this information is useful: let me know how you go!

You were able to successfully download windows files with your Mac and transfer them to your Tom Tom? I'd suggest trying the transaction again, but doing it with a windows machine. (Trust me, I have a Mac and I realize how unwell it likes to play with Windows.) {But I wouldn't trade it}

I bought a Tomtom go 720 from Australia and build in Australia Map, I want to get a USA map, do they have any free download maps from the website.

Most likely , no , unless its a special pack or somthing.

All Maps are available as installable add-ons, usually sold as a insertable memory card containing relevant map software.

So to get Australian maps on your American TomTom would just require installing the Australia Maps pack.

Hi, Answers to your 2 questions 1 and 2 . ...... 1/ go into PREFERENCES , hit right arow key till you see MANAGE MAPS , Tap that MAP icon and in there will be all the maps you have on the SD card. Select the map you require by tapping the screen. ............................................. 2/ YES , backup the SD card to your PC first. ( you should save everything on the card as it is ) Then delete the Europe map off the SD card and replace it with the USA map . You will need the authorisation code for the USA map in order to activate it. When you return you can swap the maps back again.
