Of course GPS works in Cyprus. You are able to find your latitude and longitude and altitude with no difficulties; that is what the Global Positioning System means. It is possible to obtain such devices for from about €100 upwards. However, this is not much use, as we don't have accurate maps (like the UK Ordnance Survey maps). The best they can be used for would be to trace back a route the way you came.
Without an accurate map, no one can write the software for automatic street/map display.
Even the cadastral maps, as used by the Land Registry, have enormous errors, as well as not being up-to-date, and are certainly useless for the software writers. For example, the public road I live on is not marked and the boundary along which it is supposed to run is ~50 m from the reality.
I don't know how much writing the software and scanning in the inexistent accurate maps for an area the size of Cyprus, determining one-way streets and other obstructions (and major road works), would cost, but I could easily imagine that we are looking well into the 6 figures, if not 7. Let's say £500,000. With marketing and distribution costs, that would be doubled, so that you would have to sell 5,000 at £200 each just to break even. Other than the cities, Cyprus is easy to navigate and none of the cities are big enough that a simple street map would not be sufficient for most purposes. Do you really think that more than 5,000 punters would spend £200 on the software plus as much again on the hardware? I doubt it, even if the basic precision maps were available.
