Ok, getting there, but still having a problem. Let me tell you what I have done so far.

1. Downloaded the V27.rar update
2. Un "rar-d" it with Tugzip
3. I now have (2) files: V27.mdf (huge file) and V27.mds (only 1kb)
4. Downloaded NavTweak 2.6
5. Downloaded GTK Development Environment (not sure if I even need)
6. Downloaded GTK Runtime Invironment

So now the NavTweak does open up (yeah) but when I choose File, Open, and select either the .mdf or the .mds I get "Unknown File Format".

Also, I found Paul's original file that has the i-drive logo. He has it saved as a "wave" file and said to change it to a zip. How do I do that? He said the file is really big thats why he sent it that way. Or am I ok with just using the gif image that I right-click saved from one of his posts.

Man my wife thinks I'm nuts and is gonna kill me if I mess up her Nav. But if I'm gonna do the upgrade I want the custom splash as well.

Thanks again for taking the time to help me.
Mark
