URVOLAX Android 13 Car Radio

Here we will show you how to install the URVOLAX UR92A Android Radio * step-by-step in a VW Golf 5. This guide can be applied to almost all cars that have the 2-DIN size for the multimedia unit and are being converted to 1-DIN.

Step 1: Prepare the URVOLAX car radio

Prepare the car radio in its disassembled state so that it can easily be connected with Plug-and-Play.

To ensure that the device functions perfectly without any potential issues, insert all the included adapters into the radio, even if you may not need all of them. However, the included external microphone is optional and can be skipped if necessary, as the Android radio already has a built-in microphone.

Since we will be using the external adapter for the main wiring harness in the Golf 5, we do not need the main wiring harnesses included in the package. In this case, plug one end of the external Quadlock adapter into the CAN-BUS decoder and the other end into the Android radio.

Step 2: Properly remove the old radio

To remove the original Golf 5 radio, you must first pry out the upper compartment using a removal tool and unscrew a Torx screw. Then, you can remove part of the upper trim and unscrew the next two Torx screws.

After that, you can simply unclip the upper dashboard. The lower panel is secured with two Torx screws and can also be easily unclipped after unscrewing them.

Now, simply unscrew the four visible screws that hold the radio in place using a Torx screwdriver. When pulling out the radio, you also need to slightly bend the two side “plastic stubs” to remove the old radio.

Then, disconnect the Quadlock connector by simply pushing the lever up and pulling the connector out. Finally, remove the antenna connector and unscrew the grounding from the old radio.

Step 3: Installing the 2-DIN to 1-DIN adapter (trim)

The next step is to secure the external trim (2-DIN to 1-DIN adapter) with the four screws previously removed in the radio slot. The holes are perfectly aligned, and the metal frame provided by Urvolax can easily be inserted into the trim. Unfortunately, the practical compartment in the second half of the trim will be very limited in use due to the size of the screen.

Don't forget to reattach the previously installed trim (which surrounded the old radio). Once the new radio is fully wired, you won't be able to place the trim over the large screen anymore.

Step 4: Wiring harness

We generally recommend routing the USB ports into the glove compartment and leaving them there. This placement is the easiest, and the ports remain easily accessible when needed.

Since you have already completed most of the wiring in Step 1, all that remains is to connect the external adapter (Quadlock) and the antenna. When using an external Quadlock adapter with a CAN-BUS decoder (which is usually the case), you should leave the connector with the red and orange cables unplugged. This ensures that your permanent power and ignition power continue to function correctly for turning the radio on and off.

If you want to use FM and AM or have an antenna amplifier, you need to purchase an external antenna adapter. We are satisfied with FM only and plug the antenna adapter provided by Urvolax (Fakra to ISO) into the darker Fakra socket.

Step 5: Install the URVOLAX Radio

You can now simply insert the connected radio into the upper compartment of the 2-DIN to 1-DIN adapter, and you're done. Check if everything is properly in place and turn on the radio. The first startup may take a while as the radio updates its configuration.

Step 6: Factory settings & Test

Almost done! You just need to select the correct CAN-BUS interface. To do this, navigate to the hidden menu under "Settings" → "Factory". There, you need to enter the password "123456" and then select your respective CAN-BUS interface and vehicle model from the menu.

If everything worked, you should be able to capture and display vehicle data such as open doors or engine RPM (if available).

If it didn’t work, you just need to try other interfaces and go through the options. One of the interfaces will definitely work. Otherwise, the information on the CAN-BUS decoder will also help you.

Step 7: Install DAB+ Antenna

Remove the trim from the "A"-pillar on the passenger side. Then peel off the protective film from the black film and the transparent film. Stick the black film onto the metal of the "A"-pillar and the transparent film onto the windshield. If the metal of your A-pillar is painted, you should scratch off some paint to ensure a connection with the car's ground (paint does not conduct).

Then secure the cable along the A-pillar and route the USB cable to the glove compartment, and reinstall the trim. Be careful not to damage the black film. Finally, plug the USB cable from the antenna into the previously routed USB port in the glove compartment. Also, use the 4-pin USB connection, not the 6-pin USB connection.
