Audi A3 8P (2006) mit Radio BNS 5.0 - hier USB-Schnittstelle und SD-Card nachrüsten

These instructions describe an example of how you can install a USB stick and SD card adapter in an Audi A3 8P (2006).

You can retrofit all Streaming Boxes in a comparable way.

In this example, a BNS 5.0 radio is used. These instructions can also serve as a template for retrofitting other radio models, e.g. Concert 3, Chorus 3, Navi Plus RNS-E, Symphony 3, Symphony 4, etc.

First the radio is removed. To do this, simply slide the removal tool provided into the 4 marked slots. When these are snapped in, you can pull the complete radio unit out on the hook.

The glove compartment lighting is now removed. This is only lightly clipped on and levered out on the right-hand side. The connection cable for the adapter is laid through the opening in the lighting in the direction of the radio. In the radio slot you can check whether the connection cable is arriving there correctly. If you have difficulties, you can use a wire to stabilize the cable.

If the cable can be seen successfully in the radio slot, you can already plug it into the slot provided on the rear of the radio (see marking). The connection of the earth cable with ring eyelet is very important. Screw this to the radio housing, for example.

You can now slide the radio back into the slot (not yet fully snapped in).

Here you can see how the connection cable of the USB adapter was laid from the radio towards the glove compartment.

To ensure that the cable fits through the opening of the glove compartment lighting and is not damaged, a small recess is ground into the housing of the lighting. This means that all of the lighting is retained.

The glove compartment lighting can now be snapped back into place. You can clearly see how the connection cable of the USB adapter comes out there.

The USB adapter can then be connected. If you have installed an existing CD changer, you can connect it using the empty plug (see marking) and control it using the switch on the cable.

If the switch on the adapter cable is set to "MP3", the radio should automatically recognize the adapter as a CD changer. So you don't need any additional coding or the like. Information on equipping the USB stick or SD card with MP3 files can be found in the documentation and instructions.

If the complete function of the adapter could be ensured, you can let the radio click into place again.
