External Accessory Interface
Pop-Port System Connector
Because of NMM-3’s shape, there is one deviation from the Tomahawk (pop-Port)
mechanical interface that affects an in-car holder solution: The charger jack will be
mounted remotely from the system connector.
The charger pin on the Pop-Port interface is not connected. This prevents a possible con-
nection between charging accessories, and chargers connected into a separate DC charg-
ing jack. Pop-Port chargers are not supported.
