My Reatta has an original AM/FM Cassette. The cassette is dead and I want to drop in a CD unit. It was an option i think on the '91. The units are the 1.5din, what are available interchanges? The original unit has a small Graphis Eq, if that helps. I have heard that the same unit that was available in the full size cars from 90 to 95/99 would work but those seem to be rare/hard to find. An aftermarket unit is out of the question as I want to keep my Reatta as close to period as possible. Any help would be greatly appreciated.
