Alpine CD Receiver (CDA-7873) Repair Manual?

The CD player part of this receiver has not work for a long while and finally would like to fix it. Would anyone have a manual or point me to someone/somewhere that would. It was in my car that I totaled and it actually worked once after it was put ino another car. But, now the mechanics inside grind, ect. So, just curious if anyone has a some info I could use so I can repair it.

Thanks!
