I have a very simple patch request, that may not be so simple to do.
When in a call using BT, I only want the speaker to use BT. I want the mic to use the one in the phone. If there's any difference in mic settings between a 'regular' call and a speakerphone call, the mic should behave as though I'm on speakerphone.
The reason is that I have an inexpensive BT head unit it my car with a TERRIBLE mic. I can hear other people just fine, but I have to yell for them to hear me at all. On the other hand, with my Pre on the touchstone in my car I can use the Pre's built-in speaker phone and the person on the other end of the line can hear me fine, but I can't hear the pre very well.
