Volkswagen / Skoda Bluetooth Programming

There are a number of steps to programming your bluetooth after installation, you will need access to VAGCOM/VCDS to perform these steps although your local dealer may be able to do these by using his VAS5052 dealer tool but it will be more difficult then using VAGCOM/VCDS.

Step 1 – Program the CAN Gateway to allow the controller to use the gateway.

CAN Gateway – Controller 19

This controller uses Long Coding, recoding should be carried out using the Long Coding Helper built into VAG-COM. Select Byte 3 and put a tick in Bit 7 to enable Controller 77 Telephone. Write the Long Code back to the car.

Step 2 – Setup the telephone controller to function as per the settings chosen.

Telephone – Controller 77

The controller soft coding should be set to 0000422

Step 3 – Multi Function Steering Wheel – Voice activation (optional)

If you car is fitted with the Multi Function Steering Wheel you can modify the mute button (* on the VW models) to activate the voice dialing feature. The phone button under this button is not usable at this time as this is designed to operate with the fixed car kit unit.

Controller 16 – Steering

Select Coding 07 and you should see a 7 digit softcode which will be in the format 00xxxxx

The 4th digit from the right corresponds to the steering wheel variant. If you have a 4 spoke Multi Function Steering Wheel without the Cruise Control buttons it should be a 2. Change this to a 3 and that should convert your Mute button to activate the Voice Dialling.

Volkswagen Skoda Bluetooth Car Kit Install in Volkswagen Golf

VW / Skoda Bluetooth UnitVolkswagen in Australia and other countries offers a parrot car kit as their “OEM” car kit and don’t offer the excellent VW/Skoda fully integrated unit. The units are available from a number of sources in Europe and the US.

Part numbers for the kit include

  • 1Z0 035 729 (1Z0035729) – Interface Unit (older models don’t support the RNS 510)
  • 8P0 035 503 E (8P0035503 E) – Bluetooth Antenna
  • 3B0 035 711 B (3B0035711 B) – Microphone

  • Wiring loom – Strongly recommend a full plug and play unit

Bluetooth unit prior to installation. The 1Z0035729B as shown is compatible with the RNS 510.

Tools required for the install include


Wiring Harness

There are a few options here to connect the bluetooth unit to the factory harness behind the headunit.

  • purchase a fully built plug and play harness
  • build an inline adapter and connect to the harness that comes with the kit so you have a plug and play harness as above
  • use connector housings and repair wires to plug inline with the factory headunit harness
  • cut and splice (not recommended)

Plug n Play Harness

A problem with the Plug n Play harnesses is that they don’t have compliant CAN bus cabling which has to have a twist maintained throughout. The solution is to replace it with CAN bus repair wire.

Connector housing and repair wires

This process involves joining the connectors to the harness and doesn’t involve adding bulky adaptors or cutting the harness.

  • 1 x 000 979 133 (000979133) – 1mm repair wire – CAN bus Hi and Lo female.
  • 1 x 000 979 134 (000979134) – 1mm repair wire – CAN bus Hi and Lo male.
  • 1 x 000 979 225 (000979225) – 2.5mm repair wire – 12v and ground female.
  • 1 x 000 979 226 (000979226) – 2.5mm repair wire – 12v and ground male.
  • 4 x 191 972 701 (191972701) – Housing
  • 4 x 191 972 711 (191972711) – Connector Housing

Splice

Splicing the cables like shown here is not recommended.

Bluetooth Interface Unit

Remove the two carpet squares that are premarked under the drivers seat using a small knife, don’t cut too deeply or you will cut into the paint on the sheet metal underneath. Insert the two plastic plugs and screw the bracket into place. Note that the bluetooth unit in this photo is upside down. Before you slide the unit in bend the metal bracket inwards so that it holds the unit tightly to prevent rattles.

Next remove the sill panel trim on the right hand side of the car, this only has to be removed for the front door and requires the clips to be removed so the edge of the carpet can be accessed.

The next step required the installation of the microphone.

Remove the dash vent (or tray on non Climatronic units) by following this guide.

Remove the trim around the head unit using this guide.

Volkswagen Golf Centre Dash Panel Trim – Removal and Installation

Remove the headunit by unscrewing the 4 screws and carefully sliding it out, watch out when the unit is released as it could drop and scratch the climatronic.

Release the cables from the rear of the headunit and put the headunit aside safely.

The unit that I installed came from the UK, contact the owner of this site to purchase a kit.

Another installation guide is available from his website.
