1.6 is fast. and direct BT connection. Its Great. One drawback. i was using Jet BTFExt and VC over BT with 1.5 and not only did it work, but i could leave the BT w/o connecting to VC and listen to the radio, Sling box, etc . Cant do that now. When VC ends, so does BT connection. Anyone know a way around this?
