Medion 96800 Pna250t Speed Camera Updates

Hi there i'm wondering if anyone can help?
Were looking to install speed camera update on the above machine I know the site to be looking at is www.navigating.de but there are 5 different versions of software and were not sure which version we have. Can anyone help tell us which version we need?
Thanx

There are different files for different software e.g. TomTom uses .ov2 files. You'll get loads of info from http://www.pocketgpsworld.com/module...ums&file=index
