A friend of mine has an rns-d (I think) that when trying to upgrade the radio firmware did not work anymore. The screen with the red indicating "wrong software". I've tried other firmwares from the Internet and put a cd maps DX to see if works but still see the same mistake ... I do not know what else to try, someone will have some tips?

I don´t take a picture, but I found one in google:

The radio is like this:
ImageShack - Online Photo and Video Hosting

The rns-c is not equal?
He could have put this firmware by mistake?

The firmware I used were for the RNS-D version.

Thanks for the help!

I used google translate, sorry!
