For all Streaming Boxes in VW Caddy with radio RCD 210 - retrofit USB stick, SD, Bluetooth, AUX interface

These sample instructions describe how you can install USB and Bluetooth (here: USBN15 - USB Bluetooth Interface) on a CD changer interface in a VW Caddy with RCD 210 radio. You can also use these instructions to install all Streaming Boxes.


Described as an example for the RCD210 radio - similarly usable with all other radio systems for the Caddy / Golf (e.g. RCD 310, RNS 300, RNS 310, etc.)

      VW Caddy - RCD 210 radio - remove the panel around the radio

First, the panel around the radio has to be removed so that the fastening screws of the radio can be accessed.

To do this, carefully pry off the cover around the radio with a suitable object. For example, our removal set with panel wedges is also suitable for this.

Now attach the ground cable to a suitable screw on the radio housing.

Here the marked screw is suitable for connecting the ground cable.

The ground cable can be screwed under the existing screw with the attached eyelet.

      VW Caddy - RCD 210 radio - retrofit USB connection

The USB connection can now be relocated to the desired location, depending on personal requirements.

In this example, the USB connection has been relocated behind the storage compartment below the radio so that it is easily accessible there.

For this installation method, the storage compartment / ashtray must first be removed.

Then the cable can be laid behind it and the USB connection can be led out underneath.
