Question about Car Audio & Video
I have a Sony EXCD-3RF 10 CD changer in my car. It worked fine until a few days ago. Now, when I turn the Sony head-end unit on and select CD, it loads a CD, hums away for a few seconds, then says "Error" on the head-end unit display, and goes to the next CD, loads it, and repeats the "error" cycle. I took it out, and blew out the insides with compressed air, re-installed, it and it does the same thing. I tried with with a different magazine - no change.

Your CD players' Laser Pickup unit may have damaged; or its strip wire going to the circuitboard had broken carbon tracks in it. Anyway it doesn't pick up signals that pre-burned onto the CD. Sometimes the laser diode inside it have damaged, resulting no Laser Emission. You just take it out from the car and open it carefully, and clean the lens of the laser assembly with some soft material like flannel or with an ear bud. Never use any kind of solvents, since the lens is madeup of very high quality plastic material; hard solvents may damage it. Blowing compressed air only removes any dust, not any fungus. Normally the lens get a type of fungus, that will make it somewhat opeque, and the reduce its reflecting sensitivity. Replace the flat cable fitted from the Laser Unit also. Make sure of its connections while buying a new one. Some of them has special type end connections, and look it keenly when buying it. Same side and opposite side connections are present in different type of CD players.
Now your CD player have the fault, that it doesn't detecting the lead in trak of the recorded CD. It may surely be the fault either to Laser Pickup Unit or the strip wire to which it is connected to the circuit board. Ok.
