N1116, - failure of another D2B unit, what is the numbers after that (tells which component has reported a fault)
B1010, - low battery at some pint
B1736 - fault reading CD
B1738 - GPS fault - again we need the number after that in the fault list
You should probably clear the faults (hold MUTE+0) and see what comes back
I'd try a CD cleaning disk on the CD drive (one with a small brush and very very small drop of cleaning fluid)
