That's what I thought too so I contacted GROM and they gave me dongle reset instructions and the comment that it should work. I tried it with a friend's Bionic and all the profiles are working. HSP, A2DP, and AVRCP. Seems to just be my phone. I checked /system/usr/keylayout/AVRCP.kl and all the key bindings are in there, just not being acted on.
