There's quite a push to link GPS and tourism, most notably on cell phones and devices users already have in hand. In New Zealand one hardware/software combo combines a GPS and a delivery system that interrupts current radio to fill in the driver and passenger about landmarks whizzing by. Tourism Radio is aimed at rental car agencies and many have already signed up.

I think we are moving away from "specialized devices" for content and aiming toward a single interoperable solution (even if we must pay for some content). I don't expect this type of solution to last long; it should be part of the nav device or the radio, if not the phone!
