the antenna is working properly - but not magnetically sitting in the radio slot on the radio. That's what I tried first (Ford Focus 2009 Blaupunkt), but had constant misfires in the GPS positioning. So that was unfortunately not to be used. If you can hang it on the cable it works well (always 6-7 satellites), but it is good of course, more than the test operation. I do not know where to put it, so I'll probably bite the bullet and let me replace the original antenna ...
