RAM has a PDA mount with adjustable sides 2 solid hooks on the bottom with th top 2 spring loaded. I've used the same mount for all my phones. I'm not a big fan of heavy duty cases as my phone lives with me.
Personally when it rains or is stupid hot it goes in the top box. The Bluetooth works just the same. For long trips build bigger play lists.

Bikes are like women. What you think you want, and what you want, change after the first ride.
