CD Changer madness (E46)

[Insured By Mafia]

Dear Folks/Sifus,I've been experiencing some issues with the original cd changer since the day i got the car..-Initially, i was unable to eject the magazine (stuck) / player unable to read the magazine as well..-Managed to get someone from an accessory shop to remove it for me (no symptoms why it was stuck).-Confirmed no more cartridge stuck issue but player still unable to read the magazine.-all of a sudden, 1 fine day it worked..i realized somehow the whole system got reset after battery was disconn/reconn for some aircon works to be done.-Each time i eject the magazine to insert new cd's, the original player fails to recognize the magazine "no magazine"..it seems like if i wana change some cd's in the magazine, i'll have to disconn/reconn the battery every single time i eject the magazine..Eventually I gave up on the cd changer, no more ejecting the magazine..Besides changing to a whole new player, is there any other solution? What might be the contributing factor?I prefer to maintain the originality of this car..Pls advice sifus..Thanks in advance..
