What is the priority for a SR10 connection to a 10U?  The 10U normal priority is summarized as I understand it:

HFP/Phone
Intercom
Music Sharing
FM
A2DP BT Music

Does the SR10 connect as HFP?  Or what?  Where does it's connections fall out in the priority list?  What happens with a Radar detector output connected to the SR10 alerts and you are having an intercom conversation?  If the SR10 does override, how long until the intercom is re-established?

Also, is it possible to set the SR10 so it is "always connected" and it's Bluetooth connection does not drop, so there is no delay sending a Radar alert?  And if so, does that affect the 10U already marginal battery life?
