Posted in another forum, and recived some usefull advice.

:o

I'm used to TomTom, but a friend asked me, if i could update his Navigon, with some new maps.

It is a
Navigon 5100 | 5110
Version 6.5.1 build 380
CeVersion R06US.3.0618
Program: 070821-1155

Dansish laungage

It has a .map file named
Europe_NT200708.map
And a folder named
MN6
and
RealityView

Can anyone give me a short guide in, how to update the map and/or the software?

I can't figure out wich files - i am totaly lost

Your answer should have been: "No, I cant update your gps!"

Because it can't be done - or because i don't know how?? (or you don't know, maybe?)
