Yoper Bluetooth Kit Compatible with Mercedes-Benz MMI Car Interface Adapter iPhone Android iPod Integration Music AUX Connector

was easy to install and it worked

Only had it 1 day but if it continues like it worked today, I am very, very happy. Installed with (simple) directions in about 3 minutes including pairing my phone. Thank you.

Ordered for a Mercedes SL400; would not sync and after several attempts the Radio Media Info Screen Display started showing black lines/spots. I returned it and am sorry I bought it.

I'm pleased it worked for audio. I haven't tested phone yet (but it looks like it'll work on initial setup) and I tested audio. I needed to select the boost option in my car to make the sound levels impressive, but it worked thus far. Updates to follow after getting the USB port to function. Initial test with USB SC drive attached to adapter connected to the end didn't seem to work, yet, but I only tried for like 2 minutes. Audio works great though, and I could play YouTube videos downloaded to my phone. More to follow. I get the USB dongle to work with a USB disk and the phone works, then I'm going 5 stars.Vehicle tested: 2012 Mercedes-Benz GLK 350 4Matic (built at South Carolina during November 2011).Tests completed successfully (day 1): Bluetooth pairing, Bluetooth audio (using MB AUX setting). It was childsplay: simple plug and play/Bluetooth pairing requiring no codes or passwords (though I did rename it so I'd know which device I was actually paring to).Tests remaining: Bluetooth phone, USB MicroSD disk (using MicroSD to USB-A adapter at the end of the MMI dongle), and audio quality/volume levels using the MMI interface.Quality: In just a 5 minute test the sound was good on audio playback via Bluetooth. I'll get the meter and test BT volume vs. CD disk vs. on board HDD tomorrow.Preliminary results: In my vehicle it was deemed functional/acceptable.

I got this to replace an older Auxiliary Bluetooth connector for my older vehicle - the old one had significant troubles connecting automatically to my phone and often would drop out or pause in the middle of a song. This device completely fixed those issues. Very pleased.

It works...easy to install. If you use the USB outlet you have to press the button on it to switch from bluetooth to usb and press it again to switch from USB to bluetooth... the bluetooth sound quality is ok...I have 2 12's speakers and a 3k taramp and noticed the sound quality isn't the same like the music I have on the harddrive.. not sure if that's how bluetooth is or not.. I was streaming from my phone and i bought a tablet just for the car for music, movies and videos but the sound isn't as full. Even bought a napster subscription and still the same.. I give the quality 4 out of 5 stars.

This works ok, and I can plug my USB flash drive into and the radio will play the songs just fine. The only issue I have with it is that every time I get in and start the car, it defaults to Bluetooth and I have to open the glovebox and physically hit the mode button to switch it to USB. Big pain in the butt.

Exact fit!
