NAVI question: target entry?

Hello Volvo fan community, drive an S60BE with the Volvo RTI-Navi. Have a question to you that concerns the handling of the target entry. I miss two useful functions that I know from other manufacturers: — entering the road without a house number. According to the manual it should work. Navi then steers to the middle of the road. Unfortunately, it has never worked. I don’t come out of the menu and can’t start the navigation without a house number. Am I perhaps “too stupid” to operate? 😉 — Selection of the “city center” if I don’t want to specify a precise street name. This doesn’t seem to be possible. But I find it very helpful if I drive a (exit) place that I don’t know exactly where it is located. Then I just want to be directed to the city/town center to get closer and continue my “excursion” from there. Before I select an exact road from which I don’t know exactly where it is located (city center, city edge etc.). There must be something better? Does anyone have ideas or solutions?
