It looks to me that your car has the GPS antenna wiring. The GPS antenna goes on the roof (fin on roof) - have a look at the wiring and see if something is disconnected there or whether you just have a wire waiting to be plugged in and have to change the roof antenna

That antenna you show is the retrofit antenna , but the little connector adapter is for NTG2/NTG2.5 - your car has NTG4 so wiring different
