How do you use your iPod with tomtom?

Personally, I'd just use it as an iPod, I'd rather put them all on my TomTom as well as my iPod; it saves money. You can also use the TomTom Car Kit: http://www.theiphoneblog.com/2009/08/17/tomtom-car-kit-compatible-ipod-touch-gps-apps/ It's a GPS antenna that uses the TomTom GPS App for your iPod Touch/iphone to put a map on the iPod display. You can also use other apps.
