From a quick search i did, i realized there were a lot of ppl asking for a good GPS which details Cyprus..
In case you still interested of where to get one,
www.prestigioplaza.com has the newest detailed CYPRUS map on their GPS plus for 26 other european countries
I ve called them and they also do discounts when it comes to bulk orders such as for car rental offices... not bad eh?? with one stone, two birds --> Cyprus and the rest of Europe in your car :)
Regards to everyone
