Is there a way, via software on the AVIC to switch the speaker that the Bluetooth/Navigation comes out of. The default is set to the front drivers side speaker, unfortunately for me that speaker is a 1" tweeter and it doesn't sound rite. I could switch the front/rear outputs on the back, but Id rather not have to resort to that. If I do switch the front/rear outputs, is the same audio signal going to both?

Thanks for your help,

Eric
