Yeah, I believe you, it might fit as well, but the FACRA plug is definitely for a VW or AUDI or SCODA navigatin unit, while the WICLIC is for Mercedes, Becker APS30, Sony, JVC, Pioneer navigation units.
Looking at the images it seems that the WICLIC connector is what I need. Stats007, the item in your link looks like a WICLIC plug so that should do the job.
Just gotta hunt for the cheapest one out there.
Karlefr, that ebay item number is also spot on but shipping costs are a bit high as it's located in Germany.
Are these antenna pretty much all the same thing or do I need to worry about anything in particular?
Also, my car has a short black stub aerial mounted on the roof just above the rear screen. I believe this is part of the telephone pre wiring but not sure. Is there any chance this could also double as a GPS antenna?
