No it doesnt make any sound when i hit the button but when i insert the cartridge it makes noises and it can eject. I tried cds all ways up and down.dktorcan said:My first guess would be that your CD's are inserted upside down in the CD changer's
individual trays(I assume you have a 6-disc CD changer hooked up to your OEM head unit). I made that mistake a few times, too. Just look closely at the CD changer magazine; it shows which side the discs should be up and which should be down(if I remember well - they are kinda counter-intuitive)
Now if the CD's are inserted correctly and it still doesn't play - then it's either the changer or the connection.
When you press "CHNGR" on the HU - can you hear the changer working?
You could also test if the HU is "talking" to the changer - just press the "Up arrow"
or "Down arrow" buttons to the right of the display on the HU to see if you can select
another CD in the changer.
Let us know how it worked!
