There seem to be a number of TT media centres available, including open source like this one: http://ttmplayer.homeunix.de/page/

Has/would/could something like this work on a Navigo unit, or any other GPS running WinCE with TT installed? All the ones I've seen require the unit to be hooked up to the computer to install, so the bundled installer programs won't recognize the Navigo unit to install to.

Currently my Navigo unit plays Mp3 through the FM transmitter (which is great) but the music isn't paused when instructions are played, somewhat defeating the object of having a GPS if you can't hear it, solutions involving messing with the volume aside.

Thoughts, chaps?
