That is what originally brought the question to mind...

You asked which radios were interchangeable? I was in the same situation a few months back. My friend owns a 97 ES300 and I have a 98. My friends radio went out and I picked up a used radio from a salvage yard out of a 99. We checked compatibility and the 99 was the improved radio and fit both my 98 and his 97 with no problems. I would suggest that you upgrade instead of downgrading.(Use a 99 radio in a 98, a 98 in a 97. not 97 in 97 or 98 in a 99)
as far as the model #, I can't tell you. All I know is that the radios fit and work. I replaced my LCD which was much cheaper and easier to replace that replacing the radio.
Good luck in locating cross-reference #'s
