Tomtom 3 question about other countries

I have just purchased a HP 2210 with Tomtom 3 from Totalpa.com and I am going to the USA soon and I want to buy the software for use over in the USA. My question is, can I have both the USA and the UK map programs installed on my HP2210, by the way if it matters I have bought the extra 256Mb of flash memory. Thanks for your help.

I have never tried using in the US but it is the same idea as the Euro maps all you have to do is install the maps on another card and swap them over when you land.
