I have a 2011 Fit Sport with stock radio (non Nav) and iPod/USB port. I am installing a Scosche BT1000 Bluetooth speakerphone. The unit will be under the glovebox. I need to connect it to both switched and unswitched 12V. Any suggestions for a convenient place to tap into? Also, the speakerphone has an optional wire for muting the radio during a call. Does the stock radio have a connection for this feature?
