I have had the same question... And an extender does not connect to the OE connection, Still looking for a good solution, I would love to see pictures of what someone did.

 

it will...take the plastic OE part of the antenna off...then plug your extender or XM tuner box in.

I have a pioneer XM tuner plugged directly into the factory antenna in the rear of the car...

this isn't hard guys

 

SpaceCowboy is right, but I believe he means you need to remove the plastic BLUE tab from the XM antenna, and voila! Extend it to your hearts content

 

right on wrecker

 

Finally did it, I removed the panel in the right rear that covers the XM module. Unplugged the antenna (Mine had a tan colored connector) Once you remove that connector, it will plug right into the extension. I got a 10 foot one off Amazon for $10, after cutting a couple places where it was taped to other things, ran it along the headliner, down the A pillar, over the glove compartment, and behind the radio. Where I have the new XM module. I did put some heat shrink around the connector.
Thanks SpaceCowboy!

 

Glad you got it all set up and working!

 

good job dude!

 

Can you unplug the antenna from the back of the receiver and extend from there?
