2011 Three Low Volume on Hands Free

I have a 2011 Three WITHOUT the NAV package. It has the JBL system with blue tooth. I need to know if there is a hidden menu on this system. Yes I know about the you tube video it is a NAV system and no use. Yes I know you can adjust it with the steering wheel controls. Both the vehicle and the Blackberry are set to max and at highway speeds it is almost unusable. You have to turn off the heat and defrost fan to hear. Callers say the talk function is fine just the receive is low. Today in sleet the windshield almost froze over because the defrost was off while on the phone, not a good situation. If anyone has any insight to hidden menus on the NON NAV JBL system it would be appreciated. No I Phone and Nav system replies please.
Yes the 2011 is identical to the 2010 as far as I can tell.
Thanks in advance!

All thanks for your assistance it was a Blackberry issue. I had to power down / remove battery to reset.
The volume now is plenty loud on BT at 10 and goes up to 14 if needed.

 

Troyroy, that's because you are a NY'er and can't help yourself. Besides there is not much else to do in Troy, oh I forgot you do have new fine dining restaurant there Dinosaur BBQ! Perhaps you could post a you tube video on how to work the volume controls. If you figure out how to adjust the BT volume on the non nav system let me know. I will be traveling back to Rochester past Albany from Boston tomorrow.

 

Jim, thanks I will try my wife's phone this weekend I have not paired it yet just got the car last week. As I said all volumes a max and your right it just may be a Blackberry issue. Its great for corporate email but terrible as a phone.

 

I hope you enjoyed lunch, I found the problem see original post.
