CLS Bluetooth phone

Hello everyone. I have a 2009 CLS, and recently acquired an iPhone 3G from Apple. I was able to establish Bluetooth works, but volume over the speaker system is low, even when maxed to +2. Furthermore, there is minimal volume incease when trying to either by rotating volume knob or pressing '+' button on steering wheel. Any ideas?? Thank you.

Have you tried a different phone? If you cranked up the volume during a voice call, it probably is already set so high that the phone's echo cancellation does not tolerate more.
