i have a 2003 sl55 with a d2b fiber optic system, i get no sound from the command center and no am stations . I get the n1112 error code, no data transfer between the master and d2b component ,i purchased a d2b jumper as i get the red flashes to the amp from the command unit but nothing out, so i bought another amp same problem , with the jumper in place i cannot clear the n1112. the red light flashes at the cd changer with the jumper in place.command center is 230 820 06 89 12 volts supply is present at the amp When i look at the d2b component configuration 360 is the d2b master radio all other components are vacant ????? So is this a command center problem that you can help me with. ? Thanks
