Wireless Bluetoo-th Car Kits, AMI MDI MMI AUX Music Interface Adapter Compatible for MB B C CL CLS E S SL SLK SLS ML GL GLK R W Class

Plugged into the MMI port in the glovebox, paired with phone via BT, switched to AUX, started Spotify - all good. Could not have been simpler!

Product quality is pay for what you got. Little bit of static feedback when you're beside power lines.

Works like a charm! Using it on my S400 and an iPhone 11.

I was a little dismayed that Mercedes-Benz wasn't ahead of the curve with their "infotainment" system in my wife's GLK350. I did a little searching and figured out that I needed a second Bluetooth interface to stream music in it. (I'm a huge Pandora fan) I purchased this hoping it was the solution, it definitely is! Once I figured out how to pair it to my phone I heard an oddly accented female voice telling me that my device was connected, I switched the audio impute to auxiliary and just like magic, there was my beloved Pandora belting out the Metal tunes my soul desires! (I'm a huge fan of Disturbed and Metallica)Once paired, the next time you get in the vehicle it connects faster than any other Bluetooth device I own, it's crazy how fast it reconnects! I recommend this to anyone who has the need for Heavy Metal music that relys on a streaming platform! Two thumbs up and a double dose of Down with the Sickness!!

Best purchase for my 2012 GLK 350! It works seamlessly!!!
