hey, I have a 1994 caprice wagon that I thought i'd uprgrade the radio in, it works, but loses its memory. bought 2 delco radios from 2 different people out of 1996's, investment was minimal, both have theftlok. i know about codes, but when i plug them in they don't power up, supposed to light up and show "loc", neither powers up, put the old radio back in and it comes on. the 1994 plug fits in the 1996 radios, am i missing something? like i said, radios came from 2 different cars/owners. not out much if both are a loss, but wondering why neither will work.
any help would be appreciated. thanks.
