Factory XM Antenna on 09 Taco

Hey TacomaWorld, I am new to the forum. I just picked up my first Tacoma on Saturday and so far it is awesome. It is an 09 Double Cab SR5 PreRunner, Silver Streak of course.

Here is my question. I already have an XM subscription for a portable radio (Delphi Roady XT) The AUX connection works fine, but can I use the factory installed XM antenna on my Taco? How do I connect it?

 

I had the same question. Does the shark fin adaptor connect to my Sirius Starmate?

 

I use this cable in my 09 Taco for my aftermarket XM setup.

It's a bit over-priced in my opinion, and I don't know what the dealer charges, but it's worth not having to route an antenna outside my truck.
