Thanks for the hints Kevin, much appreciated!
Gently prying the cover away and releasing the connector for the alarm light.
These are the two torx Kevin was talking about, that needs to be released in order to release the holder and get the GPS cable correctly routed.
Was a bit worried about having an angled screwdriver and dropping the screws so instead I did what i think Porsche could have prepared from the beginning, a slice in the plastic for the connector, drawing the cable that way, without relasing anything. The slice needs to be on the right side since the connector is not as deep on that side.
The AC vents needs to come out in order to fish the cable, which was a bit troubling since the manual pictures are really unclear. I dont know if this differs between models but in my car there were two metal parts with saw teeth that needed to be bent downwards from from inside the vent with a little flat screwdriver, contrary to what i found the the internet were there seems to be models with one of these things in the middle and further back.

With the AC vent box taken out, this hole leads up to the GPS position.
With a thicker metal string it was actually quite easy to fish the cable from top and down.
The GPS puck has magnets underneath that attached nicely to the standard metal plate in the position. The connector jacks in nicely with the new neighboring cable underneath. On with the cover and no evidence left behind
