In helping somebody on the board today, I found myself at the bottom of my glove box. Who knows what papers and maps you could find after 28 years. So I found a card with the code for my OEM radio which I threw away in 1999 when I installed my Blaupunkt and a booklet that explained how to re-code your radio if your battery went dead or your radio just lost the code. These might come in handy for those who still have their stock head units.
