I asked about Sat Nav years ago, because i was told i had to pay nearly €200 for Cyprus map. I asked why , when you have a map of Europe, and Cyprus is in the EU, why wasn't it included? The answer was, Politics! I was also told that they were aware of the anomaly and were trying to resolve it. Expected "shortly". That was years ago! It looks as though someone has finally seen sense.
It uses Google maps as a base but I find it easier to use. The downside is that it shows a lot of the tracks in the countryside and it is hard to distinguish them from roads. It does NOT use them when showing you a route.
We use Maps.me app for UK and all of our travel plans since it was recommended to us in 2019 when we were going to Marrakech.
Many of the streets there don't have street names and lots of dead ends inside of the Medina.
We got stuck several times in the Kasbah district in blind alleys during our wanderings but maps.me rescued us each time.
You download the country or area map.
You can bookmark places and you don't need any data to access it once you have the map downloaded to search for places.
I still find Google Maps a little hit and miss. I wanted to find the way to the PMC hospital in Nicosia centre.
It could not find the hospital. But it could find the Santo Car Wash in the same street.
