oh ya, finding the code is the easy part, it's matching it to what you may or may not have on your car that is the problem. Mine is obviously not the original deck. People have been saying on this site that there isn't a lot of traffic here, could you imagine how much traffic this site would get if it had the option codes with pictures of what the part looks like. It would be near godliness. That pic/option list would be the Hemicuda of option code list. BTW as of right now, a list like that doesn't exist.
