Review on 🎧 Bluetooth Handsfree Audio Radio Music Adapter AUX Cable for BMW E46 E39 X5 E53 X3 E83 Z4 E85 - LETAOSK by Branden Type

No instructions came but it was pretty obvious what to do with it once I saw the back of my stereo. I'm an electronics geek so this may not be obvious to others. So far, so good! Bluetooth isn't generally the best source of audio, but it's more reliable than the barbed aux cable I use and requires less effort, so I think it's an improvement. The hardest part was removing the air ducts from the car.
