Question about Sony Xplod Car Audio CDX-F7810 - CD/MP3 Player
The error 4 in most Sony stereos is an error that comes up when the laser pickup doesn't read the disc correctly. This happens most of the time because of a dirty lens in the laser pickup. If anyone smokes in the vehicle the smoke may be on the lens causing the error code. Try a wet type CD cleaning disc to see if it helps.
