I am in the process of installing a oem nav system in my 2009 Edge Limited. I have the correct part number nav unit out of a 2009 F350. From what I have read I also have to change my steering wheel controls and install a jumper wire. Does anyone have the part # for the new controls and any info on the jumper wires. My car came equipped with sync, satelite radio,and the premium 9 speaker system. Thanks to all . My new to me Ford Edge is great.
