I'm still investigating the requirements for this download. I'm trying to install it on a replacement N900 for my wife although she'll probably never use it. By checking on my first N900, I worked out to put the Drive, Maps and Res folders in MyDocs before installing the SetupMobileMaps.deb file.

When I run the program it asks me to select a Map, but only offers me Europe. If I select that I'm told SMM10 Europe is not activated and puts up the activation screens. It's at this point I'm getting stuck. My product code is rejected but whether this is because it's a different device or because my original purchase was for UK and Ireland maps and not Europe I can't tell.

From my experience so far I can say that this is not a free copy of Sygic mobile maps 10. You will need to have previously purchased a valid license.

<EDIT1>
I did a manual activation at http://www.sygic.com/en/activate and was able to enter my product code and device ID (IMEI) number. I received an activation code but it was only for UK and Ireland as suspected.

Now I need to work out how to get SMM10 to offer me UK and Ireland maps or persuade sygic to give me a Europe product code.

<EDIT2>
In the Maps directory are files ending in .mlm (e.g. Europe.mlm). These files control what maps you are able to see in SMM10. by copying the "UK & Ireland.mlm" file onto the new device, I was able to activate it using the manual activation code I generated earlier. SMM10 is working fine now.
