69 Camarpo Radio
 

Any suggestions on a basic affordable radio for a 69? I bought a Pioneer from Best buy and couldn't get it to even light up. Had power at the harness feed into the radio and a good ground. Only thing I can figure is it's not compatible for some reason, but it's just basic electricity. Any advice on that issue, and a reasonably priced compatible radio that is known to work in a 69? Thanks very much
