Hi all, This is my first post so here goes. I have a BMW X3 3.0d 2005 that has a problem with the sat nav. The GPS hidden menu shows reception interf and ANT OPEN, possible cable or GPS antenna problem "I am hoping". I am trying to find where the antenna is located the small co-ax comes off the Mk4 in the boot and then enters the loom any help would be much appreciated Thanks in advance
