2009 radio connections

Hi all,

Wondering if anyone can walk me through all the connections on the back of this 2009 factory radio:

I've purchased this hoping to add Sattelite radio and I think all I need is the antenna. Can anyone confirm what the blue square receptacle is?

 

That looks like the same connector type as the factory antenna.

 

On the wiring diagram I have, the blue square is SAT ANT.

 

Is it a JBL radio?
I'm not for sure but I thought only the JBL version has SAT built in?
I could be wrong. I upgraded from 06 JBL to 09 JBL and all I needed was the Antenna and subscription.

 

othater: Yes, it is a JBL. What I'm trying to do is exactly what you did. I have an 08 JBL stock radio without SAT. I want to add SAT..... but don't know how. I was thinking that this radio pictured, I'd have to add an antenna, but don't know which one to get or other devices.

Any advice?
