Whitaker 24

my cd player will sometimes play and sometimes it will not seems like it wont spin the cd, and the err message flashes and spits it back ive tried cleaning but it wont even spin that cd it will spit it back out also with the err message is this common for the silverado? the radio plays all the time with no problems?

i dont want to buy a new radio/cd player cause i like the factory unit but anyone had any ideas?
