Hiya, did a quick search and obv. 6310i brings up some stuff. Didnt see this though I appologise if its in here somewhere and i'm asking repeat questions....but... If I stick a 6310i phone into my cradle without a sim installed, would I be able to use it as a bluetooth pass thru for my Xperia into the command system in the car? (05 plate E class). Just curious.
