Thought I should update in case anyone searching for a similar issue can have more info. I pulled the mic out of the A-pillar and just put it up loose on the visor of my truck. That by itself reduced the echo garble by a significant amount. I'm going to update my phone's ROM and then wipe the bluetooth profile in my stereo and see if that improves it further or not. The stereo was a display unit with the mic mounted next to it so I notice there was some dirt, etc in it that I tried to clean out. I'll report on the progress later. Thanks for the input so far.
