I just got back from a year long deployment and I happened to leave a CD in the CD player for the entire year. Anyway, I started up my car recently and the CD popped out like normal but now when I go to start the car, the CD player makes noises like its trying to eject the CD inside when there isn't one and "ERR" pops up on the display and it obviously wont let me put a new CD inside. The car manual says for "ERR" to see dealer but I'm wondering if there's anything I can do on my end to fix it.

Thanks
