Ian,
I have a 2001. There's no name on my radio/CD/cassette player to tell you what kind I have but it has the 3-band graphic equalizer built into the face. I've taken the negative battery cable off twice for different reasons and the only thing that happens is that I loose the pre-set radio stations and the PT runs a litle ruff for awhile until the computer re-leans all the settings and the way I drive.
I've nevre heard of the PT radio needing a code, but that doesn't mean they didn't make one like that. Does your owners amnual say anything about a code?
