I have no problem pairing my Samsung Galaxy S4 with the radio in my 2009 B-Class. Contacts are imported without difficulty, and when I check the status of the phone the radio reports that the S4 is authorised.
However, the next day, after starting up and the TEL button on the radio is pressed...
Just read through the manual (CL500) and the instructions for the Bluetooth module (B6 788 0000) and can't figure.
It will show my address book sometimes and then at others all I get is the 'reading telephone data' for ages.
Comand occasionally seems to forget the address book completely...
