Gopal maps

Toft

Hi all, I have myself a gopal pna 4220 medion that I got from aldi a few years ago, in all that time it's never updated the maps when I've hooked it up to the net and the maps were not great to begin with.
I looked up getting new maps for Ireland on different sites(I don't wanna pay if I can find a free map out there) but everything I find relates to TomTom and garmin so I'm assuming I got myself the satnav equivalent of a betamax.
So my question: Do I have to find a map for my exact model and make? Is there any point in me looking at the Tomtom/Garmin maps and trying to get them to work?
I'm hopeing that theres a torrent that would have the right info, with a readme that says how to use it, or an opensource library of compatible maps.
Or should I cut my losses and just start saving up for a non aldi Satnav/gps?

Any questions or answers?
thanks

For updated maps you can either pay in time or money.

If money, buy an map upgrade here www.medionshop.co.uk

If you have the time and the know-how I believe you can replace the navigation software on the box and use openstreetmap data. Have at look at http://wiki.openstreetmap.org/wiki/Gosmore.
