Any 2003/4 L332 owners out there who have installed the BMW bluetooth hands-free kit? I've never been able to get the volume up to a suitable level so I can hear the caller when travelling on the highway. I have the volume maxed out on my phone (iPhone 3GS) and can barely hear the caller. Anyone else had this issue and found a way to boost the volume or know if there is a way to control the volume as the regular volume controls have no effect.
TIA
