2000 cadi cetera radio not working ,change fuse, still not working, what else could it be?

If the cd still works then it is just a bad display in the unit , replacing the unit would be cheaper than repairing it.

anti theft? bad starter?

Radiator fan not working. Water sensor. Bad radiator. Fan fuse. No power to d fan. Etc.

Add a ground strap from the body to the engine

You need to take it to the dealer. One of the system computers is failing. I do not know that model but it could be either the body computer or dash computer. Good Luck.

I know this is an old thread, but my 2006 325i Nav screen went bank also, but the radio still played. I noticed the glove box light and trunk light did not turn on also. I was told from mechanics is was probably a CID module for $2200, even though I mentioned the glove box and trunk light light were out and specifically inquired about a fuse. The mechanics never checked the fuses, because I checked my fuses in the glove box and found the fuse 61 marked with a BMW symbol that looks like light bulb was blown. The Nav screen started back up once the fuse was changed.

change the fuse AUX.

2000 cadi deville: one fuse box is located under hood on passengers side above wheel,a black rectangular cover with a red flip down cover on one end,move tabs and raise cover, under cover is a diagram of of fuse locations. remove rear seat and you will find two more fuse boxes diagrams are under these covers also.

1988 CADI Eldorado Biarritz, 4.5 liter v8: locked keys in car, called locksmith he put inflatable air bags in door to stretch 4 space to slide his crooked metal stick in and reach pull the handles, push electric door lock button/switch and manually but doors would not open. He than pulled the keys out of ignition and out the crack. Guess what, both doors sounded like they unlocked with the key but would not open. Is there some kind of anti theft protection that kicks in when you mess the doors and locks inside? Help, I have my keys but car doors will not open. Did stretching or forcing doors open a bit with these airbags possible cause damage?
