Hello together, first I have to say once, after 3 days Volvo (our first to Mercedes, Peugeot) and 2,000 km on our holiday journey southward we are fully satisfied with the Volvo D5. Sparable, powerful, comfortable and plenty of space. Now only the children have to come to the world… So to say this first thing: The Volvo has been the best choice for us next to a 5 BMW kombi or the E-Class combi, so I don’t want to make the car bad, just because I (we) are not satisfied with the Navi. But (trotzdem)… : So, as far as the RTI-Uschi is concerned: There is my very first Aldi-Uschi still the best navigation system, what there is. And maybe still the Mercedes installation solution in the C-Class. Rechnet fast, is clear and pre-alternatively? the Aldi variant has to turn the alternative route super fast again, because because because of the relative lack of visibility of the display has missed a junction. Today, when we were on the way around Vienna. Chaos is going to me, now the easy, has to do not make the same thing, the same thing, but the same thing to turn fast again, the other thing.
