I would recommend R-link to everyone, even though you pay over-the-top to get it. Don't take the Medianav. The Medianav sound system is ok, no distortion, and the bass is not bad.
But my gripe is the Nav system. It's quirky.Firstly, there are three routing options; fastest, shortest and economy. With the routing system set to fastest you often find the route diverts off the main road and takes you through towns (and villages) if the nav system calculates the fastest route is that way. Of course, that is theoretical, and traffic flow through housing estates and shopping streets is NOT that fast, especially on market day. There seems to be no priority to main (trunk roads) except by the mere expediency that the trunk route has a high speed limit.
Secondly, unlike R-link, the MediaNav system does not have live traffic updates. Because of that, Medianav cannot be used to divert around slow or turgid locations. Medianav cannot be updated to obtain live traffic update from traffic sensors.
Finally, it is NOT possible to upgrade to R-link, post production. So one has to have knowledge beforehand to make the selection on which system to get when ordering a new vehicle.
I have now got used tothe sat navquirks, and even if I don't know there area (which is why I use a sat nav anyway) I will ignore its advice, and hope the main route around a village or housing estate will get me there just as well.
I publish this gripe on the R-link thread to help people make up their mind when ordering a satnav service for their new car.
