V551 and Bluetooth Headset

Greetings,

Well I drug out my old Plantronics BT headset last night to try it out with
my Moto V551. I was able to pair and use the headset just fine except when I
tried to use my Palm T3 to dial a number on the V551. If the headset was
paired and active with the phone the Palm could not access the phone.
Likewise if the headset was not paired the T3 had no problems dialing the
V551. It would appear that the phone keeps the headset active and this
prevents the PDA from dialing.

Is this generally true for the V551 or should I look into another BT
headset? I was able to do this with an old Sony-Ericsson T68i no problem, as
soon as the phone was dialed the PDA would drop and the headset would
activate.

Cheers
TC
