Hello, when I looked at some cars on the farm at the dealer’s house, I noticed the T-Cross. Nice part and there I wanted to see what the internet has for offers. Now I always find some with such a long outdoor antenna, but I don’t want to, but a shark antenna installed by factory. Nix from Amazon, if necessary it should be taken back into payment in a few years. Otherwise I would have found a lot at Google, that was then a Since I see here and there that time this long antenna is installed and with another one a shark antenna is installed, I ask myself: What is this? Where is this determined, whether shark antenna or not? I also know only “Composition Media”, “Discover Media” and “Discover Pro” as infotainment. But now I have heard in a review that there is also a “Discover Media Navigation”. Is that true? or babbling? Thank you very much
