Mercedes Bluetooth Adapter

Are you looking to add Bluetooth functionality to your Mercedes-Benz to make hands-free calls? We will look at a few options for adding Bluetooth hands-free phone adapters to older MB cars. Several Bluetooth module adapters are available even for older Mercedes-Benz cars going as far back as 2003.

Requirement: UHI (or MHI) System
You must have a UHI connector to install a Mercedes Bluetooth Adapter. The UHI connector is found in MB cars made from 2005 onwards. In a few cases, the UHI connector may be found in earlier Mercedes cars from 2002, 2003, and 2004.

How to check if you have UHI System

Step 1

Check if you have the TEL button in your Comand / Radio / Stereo. When you press the TEL button, you will normally get a “Tel not activated” or “Telephone is not installed” error message. This is ok. mercedes bluetooth adapter install cradle phone for iphone andorid
