So as some of you know, I recently got my TomTom ONE navigation system. There's a company called MobilNova that has a video converter and media program that allows me to play movies on my ONE. So far, I've only downloaded the free demo which only allows up to 2 mins of conversion. It accepts ram, divx, mpg (2 and 4) and avi (doesn't accept wmv at the moment). So far so good. I can watch ads and short test drives on my ONE on the road. Because it's a portable nav system, I can take it wherever I go like a video iPod lol. Edit: For any TT users out there, it works on other units except the Classic I believe. Check www.mobilnova.com for full specs. I hope Garmin and Magellans users have similar 3rd party suppliers.
