Moin, yesterday I bought a new move Up including the RCD 215 sound system with 2 x 22 Watt loudspeakers on the front two doors (standart!?). I managed to do this with a corresponding Navigon navigation system, which I updated with “Navigon Fresh” to the most acute level. When I put my Navi on the holder and then start the motor, the Navi starts but it is not possible to connect to the radio. When I connect my smartphone with the N avi had connected via Bluetooth and wanted to listen to this music, the music was played exclusively via the internal speakers of my navigation system In the manual of the RCD 215 is exclusively, which should be found under the “Media” button the choices AUX, Navi and CD. However, I can’t discover the Navi anywhere Please for help Mfg Finn Ps. In the rear area are 2 apparent speaker outputs from which however no sound k ommt. Is there something broken or missing there only from the factory from 2 boxes? Are there possibly already cables available to retrofit?
