My early 2003 4200 has screen mounted FM aerials and a bee-sting on the roof. I have seen 4200s with later registrations with the aerial mounted on the rear wing. It probably depends on what parts were on the assembly line at the time of build.
I was also under the impression that the bee-sting is the phone antenna and the SatNav aerial is mounted by the instrument binnacle, but I'm probably mis-remembering.
