1992 Sierra CDM/radio receiver

[cmc89]

Hey guys! I'm usually over in the 66 section but I'm having issues with my 92. I just bought a 92 sierra 2500 and the radio does not work. It has the stuck at 1:00 and nothing works thing going on. This truck has the cassette player with the EQ options. I have another 92 sierra 1500 that has the cassette player without the EQ options. I can't seem to find a cdm anywhere that says it's compatible with the EQ stuff. My question is can I swap/buy a cdm/receiver that didn't have the EQ option and use that? the only thing I'm trying to do is have some music while I drive. Or if I get an aftermarket radio can I get rid of the cdm all together? Thanks in advance!
