simultaneous Bluetooth headset pairing

[Guest danmancs]

I have a smartphone and a bluetooth headset, which are paired.

I am going to buy a PDA to use as a satnav system, using a bluetooth GPS reciever.

Is it possible to pair both the phone and the pda,to the headset, at the same time, so that I can be driving along listening to directions in my ear, then if the phone rings, it also rings in my ear?

Which would take priority in the event I got a call and a direction at the same time?
