I have heard some talk about the end connector of the Pioneer GPS antenna. I've never seen one like it before. I think I can see how it's put together, has anybody replaced the end connector? How hard was it? Where did you get the piece?

The reason I'm asking is that I got a little GPS antenna at a flea market- it's a Trimble 40767-40, and I paid 2 dollars for it, still in the wrapper. It has a tiny coax screw-in connector. I was thinking I could put a Pioneer end on it and have a spare.

I'm wondering the same for the Z1 Sirius radio antenna. The end matchs the 06 VW, though there is a slight difference in the diamater. I'd like to use the factory antenna, though hate to ruin the Pioneer antenna.

No, sir. The Sirius and XM antennas are not interchangeable, they respond to different frequencies. But the factory VW Sirius antenna should work with the Pioneer Sirius (not XM) reciever, but you will have to change the plastic part of the Fakra connector. Look inside the connector and see if the metal internal parts seem the same. You may even be able to just remove the plastic entirely if you can keep the connector from falling out. Now, the GPS antenna you found most likely will not work on your Pioneer, because they (the antennas) are usually gain- and load-matched to their receiver.

OH! It does seem the Trimble has a longer cord... If that's so, then what do you get when you buy Microsoft Maps and Streets for your notebook? Does it plug into a card, or does the antenna have a USB connector or something?

I believe you will have a card or some module that plugs into the computer for that.
