I would like to upgrade my 2010 Ford Edge factory 6 disc radio with sync to a Clarion? 6 disc Nav radio. I went from the stock 9T4T 18c815-GD to a AL1T 18k931-AD but lost all audio except for the sub woofer. I believe I have the premium II system with Sync. Can someone tell me what additional parts I need to get and if I will need to have the radio reprogrammed? I do know I will need to change the right steering wheel control because it has the phone and OK buttons.
