For those of us American Z4 E89 owners who did not purchase the in-dash BMW GPS option, my understanding is that US-destined Z4s have a factory-installed GPS receiver antenna behind the center roof reading lights.
...and if that is correct, does anyone know if the Fakra cable for the GPS receiver was also pre-installed? If yes, anyone know where the lead / wire travels to (despite being unused) such that I can find it and connect into it and use it with my new Android head unit?
While the reception of my Android-included aftermarket GPS antenna may be ok, it would be much stronger if I could tap into the factory GPS unit (if it exists). Thanks for any advice.
