The telephone module with Bluetooth SAP  is designed to extend the mobile communication system in your Mercedes-Benz. Just connect it to your Convenience Telephony system (Code 386) in the centre armrest, and start using your mobile via the on-board hands-free system. The telephone module features a SIM card reader. Comparable with a permanently installed phone.
Other advantages of the telephone module:
When it comes to selecting a mobile phone for your Mercedes-Benz, you’ve never had so much choice. One "click" is all it takes to replace the mobile phone cradles. It takes a matter of seconds and is as easy as inserting the mobile into one of the cradles. That means changing your mobile and even swapping models no longer presents a problem – convenient telephone technology included.
 Two versions of the Mercedes-Benz Bluetooth (SAP) telephone module are available: one in the form of a closed box (pictured) and the other with a corded handset (not pictured). Both versions feature a SIM card reader.
 Can be used with optional extra "Code 386 Convenience Telephony".
 SAP (SIM Access Profile) allows the module to read your mobile phone’s SIM card
