Lights quit working on my radio so I found a same stock radio out of a wrecked bird that only had 13,000 miles on it. Got the radio for 5 bucks but then someone said you cantjust take the original out and swap. Some code or somethjing has to be done?

Each radio has an internal security system. If the owner has activated the security system, there is a 4-digit code that is required to activate the radio after battery power has been lost. If the radio you bought is asking for a code, there are places on the internet (not GM authorized) where you can access dealer software to reset the code. I haven't seen a reference to a source in may years.

@1993TransAm is our Delco radio expert. Most likely he can help.

Local Chevy dealer might be able to straighten it out. I also seem to remember an 800 number you could call...

...there's always this too: CLICK ME!

Have you installed the new radio yet?

 

[marvin.vonrenchler]

Itys a 2002. I just got the replacement radio out of a junker in a wrecking yard. Have not touched anything yet pending finding out what to do.

I think the point is that you won’t know if you need a code unless you power it up.

Well...it may be useless. Think I just blew something in the engine. See my thread about the temp guage stopping and the fans staying on. Something else just heppened
