Yes, there is a manual available for the Mercedes-Benz Audio 20 system, as indicated in the provided context. It contains operating instructions, system settings, and other relevant details.

Regarding accessories for upgrading the radio system, the manual mentions that the Audio 20 system may support a Media Interface with an associated audio cable set. However, it does not specify additional accessories such as better speakers. For further details on upgrades, it is recommended to consult an authorized Sprinter Dealer.
