I have ordered my S3 with bluetooth prep and the iPod connection (to be installed upon delivery so as not to have the dock) I was wondering, will i be able to plug my iphone into the ipod connection, play music and connect via bluetooth to take calls at the same time? Has anyone else done this? I have a friend with a BMW 5 series and he says when he plugs his iphone into the car to play music it stops the phone function. Also, am i right in thinking you can get a cradle for the iphone? Will it fit in the arm rest preperation?
