loading gps software problems !!

hi all,
i have recently bought a fujitsu siemens n560 and seperately bought navigon 5 software for it. my problem is that when i load the mn5 software onto the pda i get the message " installation was unsuccessful.the program or setting cannot be installed because it is not digitally signed with a trusted certificate".i have gone in circles talking to navigon,fujitsu siemens and microsoft who all deny any responsibilities.

does anybody have any ideas about how to go about sorting this problem out before i take some drastic action and send the pda back from whence it came !!!!!!!!!!!

cheers , ste.

does anyone have any ideas on this ?

Since it's Navigon's software giving the error, buck rests with them in my opinion.

Have you searched Google, and google groups for others having the same issues?

i've found out that i need to turn off or get the pda to ignore the digital signature check in windows mobile media 5 , trouble is i don't know how to do this , and microsoft won't/can't tell me because they say fujitsu altered the program themselves before they sold it on,(apparently all pda makers do this prior to selling the product).

Some of the links on the following search seem to be what you're after.
