CHELINKWireless Bluetooth Adapter Audio Input Music Interface Cable in-Car AUX USB Cord for BM-W E90 E91 E92 E93

Perfect device other than the white noise buzz that plays through my speakers which can be heard over my music and now I can’t unhear it, will not be using it.

Money well spent

Installed and connected just fine, but upon switching to aux input in my car, the device sends a horrible loud buzzing tone through the sound system which also covers up any audio you actually want to hear. This doesn't happen if I plug my phone directly into my cars aux input, so it's a fault with the Bluetooth module and not my car. Sent straight back.

I used it for my bmw f10 and it makes so annoying sounds

Broke after 2 weeks
