The iPod Touch does not GPS only the latest iPhone does.
with this: http://www.amazon.com/Tom-iPod-Connect-Cable-Audio/dp/B000FEKEN4 You can route your audio out from your iPod to your 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.
No it Con not be used on a iPod because the iPod dose not have a GPS, the GPS is required so that field agent can conferm that you have went to your lactation and the exact location you have gone to.

The iPod Touch does not have GPS abilities to track your exact whereabouts exactly where you are at that point in time. However, the 'Maps' app allows you to get directions, which is technically a navigation feature.
Yes, all apps work on both devices, the only exception are apps that use GPS since iPod Touch doesn't have GPS signal receiver (and older versions of both devices sometimes have trouble too).
To hook your GPS up to your speakers you would need a GPS systems with a head phone jack. If you have a head phone jack on your GPS you can use the same plug from your iPod with your GPS system.
There is no GPS system on the iPod Touch. The iPod Touch does not have Global Positioning System capabilities at all. Therefore, there is no need to turn off what is not there.
No ipod touches have GPS receivers.
There are a few apps out there that find other iPods, but you would need to have a second iPod Touch that has a WORKING finder app.
No, but the latest iPhone does...
