The connector was in fact not down far in enough to make contact. The swinging retaining clip needs to be pushed a bit further downward before the connector goes in. And I overlooked it on both units. The DSP version MID does work as plug and play radio. However the DSP button doesn't show any options as it obviously needs the amp and coding.
