I did hear something today that I listened to with very (VERY) skeptical ears. Was told that if you have the current latest (i.e. you have the SXM apps), the update that adds Pandora, FB, etc., will be an over-the-air update.
The two of us in the room who are most technically savvy both looked at each other with wrinkled brows and quizzical smirks when that was mentioned. We'll see. Normally I wouldn't have given it any credence, but the guy from corporate who said it is usually accurate, credible and reliable.
Be patient Jack. It is coming, eventually. In the meantime you can stream Pandora from your phone via bluetooth or usb if it is an iPhone. Why you'd want FB in the car is still a mystery to me. I did talk with one FB employee who laughed but said he could see employees using it to "check in" while driving by HQ so coworkers thought they were at work even though they were out joyriding (my dealership is 5 miles from FB).
