I read where someone adjusted the mike gain for the bluetooth system on the nav screen of a 2007 camry hybrid.I think he said he set it at +1. I can not find any screen that allows this adjustment. Any help will be apreciated. Thanx.

Check out http://www.greenhybrid.com/discuss/s...ight=bluetooth. It talks about going into the diagnostic mode and changing the setting. I have not tried it.
