AwB: I have purchased the cradle (it came to: $222.36). It's NOT labelled "Media" adapter. It plays music, and I can access my telephone. The telephone connection is via bluetooth, however, the antenna is connected via the shark fin antenna that is located on the roof. Hence, significantly improving cell phone reception. I was able to test/confirm this, as I can now keep a phone call going when I enter underground parking structures. It's pretty great. THe ONLY complaint I have is that I cannot see my text messages.
I've attached a photo of the box the cradle comes in, indicating the part number. If you'd like, I'm happy to get you one and have it shipped to you. Just let me know
Cheers,
Kev.
