Will the Euro maps fit on an SD card?!

[greenock]

I want to download the Western European maps for a Tom Tom One but am concerned that a 2GB SD card won't be big enough. The Tom Tom site lists the size of the maps at 1.9GB but don't memory cards need to keep some space back for themselves just to operate? Also, if this is not a concern, is 100MB enough to store any POI's and other data I may want/need.

Sorry if these are obvious questions but I'm somewhat of a novice where all this is concerned and a quick search didn't reveal any answers.

Thanks in advance.

Just realised I've posted this in the wrong section. Told you I was a novice!

I'll try and find the right board but if anyone wants to help with an answer here it'd be appreciated.

Thanks.
