Samsung Droid Charge bluetooth pairing with Lexus GX460 bluetooth

[ebillings]

I am successful in pairing my Samsung Droid Charge bluetooth with my Lexus GX 460 sound system bluetooth. The problem I am having: if hands-free phone functions are activated while listening to internet radio being broadcast thru my droid device, when the phone function ends the sound system doesn't connect back to the broadcast from the droid device. The same scenario happens if I simply switch modes from the bluetooth connection to some other mode, such as regular FM broadcast. When I switch the mode back to bluetooth it doesn't reconnect to the droid broadcast. In order for the vehicle's sound system to reconnect to the droid broadcast I have to "restart" the vehicle's computer.
