Have a Avic-N1, upgraded to the CNDV-80MT discs and keep getting this pop up screen in the begining. I have connected the green wire to the parking brake and just grounded the wire and still get the Caution message. I also have the issue where I have to be stopped to type in an address or watch a DVD. Has anyone disconnected the cell phone wire, placed it into the wire harness open slot and grounded the wire??? There has to be a better way besides solidering a jumper on the board. I know you can do this a the Z1.
