In this video I show how to add Bluetooth audio streaming to an Audi A4 B8 using a small Bluetooth receiver connected to the car’s factory AUX input. This simple upgrade allows you to play music wirelessly from your phone through the original Audi sound system.
I demonstrate the Bluetooth module used for the installation and explain how it connects to the vehicle. Depending on the equipment level and trim of the car, there are several possible connection points for the AUX input, and I go through the most common options.
The video includes:
- Overview of the Bluetooth receiver module
- Where to connect it in the Audi A4 B8
- Different installation possibilities depending on trim level
- Connecting the module to the AUX input
- Testing Bluetooth audio streaming from a phone
This is a simple and affordable way to add wireless music streaming to the Audi A4 B8 while keeping the original factory head unit and sound system.

(second one in this listing is similar to my module but works directly with a USB charger, so basically no soldering required)
Many other similar modules that might be plug and play: aliexpress.com/w/wholesale-bluetooth-audio-module-audi-a4-b8.html?spm=a2g0o.productlist.search.0
