Wireless Bluetooth Car Kits, AMI MDI MMI AUX Receiver Music Interface Adapter Compatible for MB B C CL CLS E S SL SLK SLS ML GL Class

Perfect

THE GOOD:Shipment, Easy to use and Install - just plug and play and decent build quality. (unfortunately that's where the list ends!)THE BAD:• Doesnt go into alternate red and blue blinking as described.• Does not connect multiple devices, despite following complicated instructions of pairing multiple phones• does not switch the pairing mode as described by using NEXT button in AUX mode• Most annoying - every time you remove the key from ignition it switches back to bluetooth mode. its very annoying to switch it back to USB mode each time you start the car.• Most disappointing - the Sound quality, plays at half the volume and significant loss of quality of audio. A phone speaker would play better quality music than this bluetooth connection.• Design Flaw, the car end of the connector has the wire coming outwards, towards the door of the glovebox, making it impossible to close the glovebox without pressing against the main connector.

After ordering another version of this adapter (twice) I finally found this one and it just works. Recommend this but it's a bit of a raffle.

If you have an older mercedes as i have this gives you bluetooth streaming via the multi media connection in the glovebox.Works brilliantly.

Works like dream. Useful addition for sound system in older Mercedes. Play from USB or connect your mobile via Bluetooth.

I returned it didn’t fit

It’s strong connection

Works only on GLKs from 2011-2014. Mine is 2009 - the flash drive works, but no bluetooth. Otherwise looks good and the materials are of pretty decent quality.The seller was very polite and actually refunded me.
