Nextquestion...96 Eldo 12 disc changer loads cds (I can hearr it)but keeps giving error message. Ayn help?

 

Check connections and for codes. May need to send deck out for repair. You really need GM scanner to check out. TECH1 will work; many systems are designed to work with it, as Tech2 was not ready till 97. Tech1 requires interface adapter for OBD II.
