PDA software on Medion MDPNA200

[undernavigator]

I'm a GPS newbye. Tried to find some similar topic, but found only two with no answer. So let me try, please.
I have just bought a Medion MDPNA200 (marked also MD95351) supplied with Medion Navigator 4.4 software and a single nation map.
I have found an interesting offer for 5CD's Medion Navigator 4.2 PDA 2005 (please, note PDA), with many maps and so on. I have read in the newgroups about impossibility or difficulties with installation of software different from the one sold with the PNA (that I haven't installed yet).

Can anyone tell me if is it possible do install MN 4.2 PDA on my PNA?

Of course I have no fear of unrevealing, if necessary, the underlying WinCE.net OS.
