Just took delivery of S60 today, love the drive and everything else. I have one question/issue, does anyone know why the volume level for HD FM radio is so different than Bluetooth music on my iPhone. I turned the volume on radio to 4 or 5 and it's loud enough during freeway driving, but when switch to Bluetooth music I had to turn it all the way up to 11 or even 12! When I switch the mode back to radio, the volume level from Bluetooth scares the heck out of me and my son.
