A couple questions about sygic maps before I can buy it. I have searched all over the forums but have not found an answer so far.

1) how much space does the installed program need (i suppose it depends on the region... I am interested in europe atm)? I see that the download is 1.8GB, and i have little more than that free. If it is much more then that I will have to buy an SD card first.

2) can I buy both europe and US regions? how much will that cost? how much space will that use up? I will probably buy europe first, but if I am happy with it I could be buying the US as well soon.
