2 simultaneous bluetooth pairings?

[jalan]

I am interested in using the Blackberry Bluetooth Gateway (with my TP2) to stream A2DP music and my navigation app voices to my RV stereo using the 3.5mm aux output on the Blackberry Bluetooth Gateway.

I don't actually own the Blackberry Gateway yet, so if there is a better product, let me know.

Question is, can I use the Gateway bluetooth for the A2DP streams and still send/receive calls on my Jawbone Prime headset at the same time.

I know that the A2DP audio will not continue when I am on a call. That is fine. But can I maintain connections to 2 bluetooth devices simultaneously, one for A2DP and one for phone calls?
