Wow, what a mission.
I finally got Navtweak to work and burned my disc, thanks to all the helpful ppl in this thread.
I went to load it in and as I had previously updated my system to V32 it said 'your software is up to date' and it wouldnt overwrite it with the new data.

Suggestions as to how to get my 'new' v32 into my system would be appreciated.
