Supposidly someone on another site has gotten A2DP to work without any hacking using iMuffs w/o the adapter, just paired straight to the 700wx. I have a feeling it is BS, but I have asked a couple of more questions. I will update if I get a reply.
I did try the MSI Blueplayer software on my 700wx with my iTech clip. It sort of worked, had random skipping & pretty good sound.
