Updating Gps Maps

[abu]

Hey

I have a NAVMAN F20 GPS which I would like to update the map on, its currently running the 2006 map but I want to upgrade to the 2008 one

Can I download a map from the internet, load it onto my SD card then run it off the sat-nav?

Or do I have to buy the connectivity kit (cable and drivers) then connect it to PC then update?

Can I download maps for any sat-nav and use that or does it have to be specifically for a NAVMAN F20?

Had a look at the NAVMAN site and the maps are like $179.00.. so there is no way I am going to pay that

yes you are. thats the only real way to do it unless you know someone with a new one.

Well no I'm not

Because - I would rather sell my GPS then add the $170 that I would have spent on a 2008 map and just buy a new GPS

That new GPS would then have the 2008 map on it and it would be newer with more features
