My Mercedes 1999 s500 has a CD changer in the boot. This has stopped working and now displays the word "Magazine empty" on the Comand Screen, even though it isn't.
What is the problem, please?

inside the CD player there's a small microswitch that gets pushed closed when there are discs in the cartridge

so its very likely that this switch is damaged or corroded

to get to it the unit wiull need to be stripped down and the switch desoldered and replaced

if you're not comfortable with this then its a job for a car stereo repair shop which I'd expect them to charge about £50-80 for the work
