RNS510 with DAB and RVC

Does anyone know if there is RNS510 with DAB and RVC , i have been told you can't have both ? I have RNS510 now with maps but want to get a new unit with DAB and the option to add the RVC but need the right outputs. Ive seen there is a few models of RNS510 and wonder if one of these has all the options.

My RNS G has the availability of the RVC. On the back lower left there is a rectangle black plug for the camera.
