Car Bluetooth AUX Adapter AMI Interface Cable for Mercedes MB B C CL E S SL ML Class W204 S204 C204 W242

I love the simplicity of this device!Plugged it in once I found the slightly inconspicuous plug hole in the top left of my Glove Compartment!I already have Bluetooth connected to the car for phone services via my mobile phone... To hook this adapter up I found the new Bluetooth entry "SGBT" followed by 4 digits (on Android devices just long press on your active Bluetooth icon to display a list of currently available and/or connected Bluetooth devices).I tapped on that list entry and accepted the "Pair" option.Once that's done on your mobile device, switch on some sound source such as a music player, Spotify (in my case) or similar and start the app playing.On your Command unit move to the "Audio" heading and select that heading in order to see a list of available inputs for your Media system. I was using Radio and scrolled down to "AUX" and that's it!My very small issue with using this adapter is that there isn't any kind of amplifier in the adapter so you need to push up the volume on your mobile device quite high and then pump up the Volume on the in-car sound scroller in order to match your radio sound levels.This isn't really an issue at all, except that you have to turn down the volume again if/when you switch to the standard RADIO setting again in your AUDIO input list.Overall this is an amazing piece of kit and at a very low price and super simple to connect to once plugged in!Does exactly what I need (play any kind of Audio from my mobile phone) over Bluetooth and through the awesome Mercedes S350 sound system (Bang & Olufsen)!It connected to my phone in a couple of seconds.Of course there's no need to repeat the Pairing Process, unless someone else, or a different device, wants to stream some audio.Superb ❤️
