psyxologos - NavTweak is used to change parts of the 'navboot' file that is on the v32 disc you burned, and not map discs. It can be downloaded from the link in the first post HERE. I believe it's still free to use.

Check out post number 93 HERE for the Perspective view "Angle Wing", I changed the pointer on mine and aesthetically it is infinitely better. The open section at the top provides a clear view of the road ahead. You can also change your splashscreen, there are lots of options HERE.

However, it's probably better to get used to running with what you have at the moment and consider any further changes later.
