2005 legacy antenna location

[chrisfoot]

I have a 2005 Legacy with a Sirius radio. The radio is currently using the FM transmitter from the Sirius unit to the FM radio (broadcasting on a preset FM station).

 

I followed the recommendations on this site to install the external antenna near the third brake light so that is working well.

 

Over the last few days, the radio has been unable to pick up the broadcast from the Sirus transmitter.

 

I'd like to purchase the FM antenna direct input connector that Sirius offers. It splices into the antenna input into the radio.

 

I read the posts that provide links to Crutchfield and other vendors that provide the two adapters that allow the Subaru 05 antenna connector to adapt to a traditional antenna connector.

 

I read the posts, yet I can't seem to find the antenna input into the FM radio. What exactly needs to come out so I can install the adapters?

 

I can't seem to find this information in the various posts I've read.

 

Thanks!
