the operation of the San Diego 530 is a unique catastrophe. Not less also the instructions in the enclosed booklet. An absolute impudence is the Blaupunkt service. Call erreichnar not, and if it is then it should work once a hotline that does not know itself how it can work. It took several days to find out about the functionality of the remote control. In the manual is no indication that the Plus tab must be placed around the button cell. One offered e.Mail "Service" completes my remarks from about Blaupunkt.
