Yes, I purchased the Garmin V as well as the Saudi base map from Darmoja. Although the Riyadh map appears to be very detailed, I'm disappointed with the accuracy and functionality The AUTOROUTE feature appears not to work with the data. It can't seem to "see" the new download for AUTOROUTE so it attemps to find the grid coordinates using the major roads and then heads off road even though there are many legitimate streets to traverse. Also, when travelling down these streets, you are not placed on the roads, so often the map shows yout travelling either to the right or to the left of the road you know you are on. It is consistently off to the right or to the left, so I believe it is a map problem and not a GPS problem. When I'm on RING ROAD it always shows me in the correct location, and announces the proper names of upcoming intersections or overpasses.
I've contacted Darmoja for help on this. If this is the best it can do, I wouldn't spend the extra money on the Saudi map unless you are happy being located within 30 meters of a street corner.
