Ok, this may be a pretty stupid question, but is there any way to update the maps on an F20?

If not, is it possible to run any particular satnav software on it, such as iGo, TT, Sygic etc... & how do i go about it?

I'm not a total beginner in this, i've got a F&H GPS35LS running iGo Primo, which was previously running on an N30, which packed up just before Christmas.
