I'm installing an old Kenwood KDC-MPV7019 head unit that I've had kicking around in my basement for years into my 2003 GMC Envoy because the factory CD player finally quit on me. I have on-star but no Bose sound system and therefore used the Metra GMOS-01 Module to keep all the safety chimes and on-star working.
I got everything wired up correctly (I think) for the Kenwood and everything seemed to hook up nicely in my truck but when I turned on the power the display reads "CODE ON" and then prompts me to enter the security code...once entered it reads "ALL OFF" and nothing works.
I can get into the menu/settings and I've read the manuel a hundred times over and can't figure out what the problem is.
Has anyone had this happen and/or know how to fix it?
