you know screens like this :
http://cgi.ebay.co.uk/ws/eBayISAPI.d...MEWA:IT&ih=013
they advertise they can be used with sat nav,
well im wondering how you get them to work, i assume theres no gps receiver in them so you would need to add that, also no software, so ho does the software work?
does a slave machine running the software connect to the unit to just use as a display device?
i cant find any information,
im getting a unit like that i posted anyhow for dvd duties, and i run tomtom navigator on the pda, so im wondering if it would be cheap to get tomtom running on it.
anyone actually know for sure how they work?
