Just because your Mercedes radio does not have a dedicated AUX input does not impede streaming apps from smart device.

Thanks to the A2D-MBFM, these Mercedes vehicles owners can user their smart device to stream directly into factory radio. The direct connection eliminates most static/interference that can occur when using wireless FM transmitters. All the driver has to do is designate a radio preset as a “streaming channel,” (87.9 or 88.3MHz) turn on ignition, pair smart device and enjoy favorite streaming service (e.g. Pandora, Apple music, Spotify ), GPS app (e.g. Waze etc.), Podcast etc. with excellent sound quality and unlike FM transmitters; you won't have switch between stations when traveling through different areas. Switch ignition key to "ACC" or "ON" and the Bluetooth module interrupts incoming antenna signal, delivering a strong signal from smart device.
Installation is also a breeze and only requires connecting the radio antenna into the module and plug module into the antenna socket on the rear of the radio (Antenna adapter included). The A2D-MBFM provides FM radio quality sound and is a great addition to Mercedes radio lacking dedicated AUX input.
