2008 E350 Bluetooth and HTC EVO phone
 

I just bought a 2008 E 350 and need to buy the puck "dongle" and set up the bluetooth. It is important that I have the best reception and as many features as possible for my bluetooth as I work out of my car many hours a day. Can anyone lead me in the right direction as to which dongle will work best with my EVO phone? Thanks!!
