Something else I forgot to mention or need clarification on: I plugged in an Audio 30, BE6003, which I believe is from a second gen (CANBUS) W210 to the 1998 wagon. It powered up and worked perfectly. Becker lists this radio as being for a 1999-2002 E-class vehicle, along with the 3302 and 3309.
Could the BE6003 not be a CANBUS radio? It’s got pins in the CANBUS positions in the third connector. I hate to beat this to death, but I’m just trying to understand if there are variants of this model that will work in the 1998 wagon.
