as in the tyre make?
everyone is having a go at making and selling these units thinkin theyre an easy profit market. its not even cheap either which gets me thinkin. with technology like that a reputation and future support is a must
if you wana take a risk with this one i would firstly find out who makes the maps and how good are they? guarantee length?
for that sorta money you could buy any of the makes on the market, garmin, tom tom, navman etc
