Have several of these from a junkyard. They take the regular delco
wiring harness and all take in and eject cd's but have no other
function. These are the first delco radios I've seen that won't power
up with GND, BATT & ACC hooked up. What am I missing here?

Sounds like it might possibly be theft protection. Once disconnected
you need to put in a code, and you need to do this even if the battery
dies in the car !

This is another case of something that is supposed to be good for us.
If your radio gets stolen the crooks get nothing, but your insurance
pays out $500 or so and raises yor rates. See how good it is for us ?
Of course now you might be able to get parts from these stolen units,
but Murphy's law might kick in and give you a bad transmission. In
younger days I changed many trannies with $60 replacements from a
boneyard, but I 'm sure that whatever changed that was something that
was "good for us".

Some newer Delco radios lock to the vehicle by data and some have no
ACC connection these units will not power on unless cleared and
installed in a vehicle (now it will lock to that vehicle) also they
might need to be reset to the new system if it has any differences all
done with data and controled by Delcos tech 2 with computer setup,
check with local dealer.
