1G factory stereo

just installed a factory am/fm/cassette/cd with the built in eq and has the factory amp. bought it on the net and it all works except the tape player. looking for anohter setup like it or the radio tape part to make a complete one. seller says i can return it which is ok but we really liked the looks of the factory unit adn were satified with the sound after the speaker upgrade. anyhelp would be great.e-mail is [email protected] and i'll check back here. thanks, steve
