For radio and radio navigation systems without diversity function, the aerial system consists of a window aerial in the rear window with an aerial module.
For radio and radio navigation systems with diversity function, the aerial system consists of a window aerial in the rear window with two aerial modules.
Golf saloon: for the optional reception of “DAB”, digital radio reception, the window aerial in the rear window is equipped with a special aerial module.
Golf Plus: for the optional reception of “DAB”, digital radio reception, the window aerial in the rear window is equipped with a special aerial module.
For equipment with navigation, telephone or auxiliary heater remote control, an appropriated roof aerial is installed.
The aerial system with diversity function optimises and improves reception in the vehicle.
Diversity functions are directly executed in the radio unit or radio navigation system. No additional aerial selection control unit is installed in the vehicle.

The bluetooth car kit is built around a TDA7590 a high performances, fully programmable 24-bit, 120 MIPS. Digital signal processor (DSP), designed to support several speech and audio applications, as automatic speech recognition, speech synthesis, MP3 decoding, echo and noise cancellation.

Nevertheless, the embedded CODE Cs bandwidth and the generic processing engine allow to proceed also full-band audio signals. The large amount of on-chip memory (128 Kwords), together with the 16 Mwords external memory addressable and the 32 general purpose I/O pins permit to build a DSP-system avoiding the usage of an additional microcontroller.

The presence of serial and parallel interfaces allows easy connection with external devices including CODECs, DSPs, microprocessors and personal computers.

In particular, the debug/JTAG interface permits the on-chip emulation of the firmware developed. Further, the presence of the timers and watchdog block makes TDA7590 suitable for PWM processing and allows the integration of a system watchdog.

The install process is simple, using double sided tape stick the GPS antenna in the location shown and press down, wedge some foam on top and tape the GPS wires down to prevent them interfering with the diffuser vent (for cars fitted with climatronic). The photos show two GPS antennas installed side by side and there is room for two more.

This guide uses an off the shelf switch and no-one would know the switch is there unless they press the button. Whilst this guide is performed on a Golf Mark V the same blanks are used in the Golf Mark VI so the same switch can be used and the same principles can be applied to any other car with a similar setup.

As an alternative there is a company called CarStyle4You that sells buttons with different engraving that match the OEM buttons and they also sell suitable oem switches. See the end of this guide for their details and a few sample photos.

The switch used here is a latching switch but momentary is also available. The switch illumination can be used but as the ends are removed you will get white light spilling out the sides so upgrading the internal light to a coloured LED gives a nice glow around the switch.

The switch used to be available from RadioShack in the US but they don’t seem to carry them anymore.

To allow the blank to fit and move freely the two sides of the switch around the cover of the switch must be removed, not that the base width must not be altered as it’s a perfect width for the centre console.

Fit the switches and align them on the front (there is limited adjustment) and screw the retaining nut down tight. Once aligned use some two part epoxy (araldite or similar) to lock it tight and prevent the retaining nut from working it’s way loose. The wires have been taped up using Fabric Adhesive Tape for wiring looms and harnesses and connectors fitted around 300mm down to allow easy removal of the central console.

For various reasons including power drain issues with third generation head units or the addition of new unsupported modules the CAN bus gateway must be upgraded to a newer revision. This guide covers the replacement of the CAN bus gateway in a 2005 MY06 Volkswagen Golf GTI. The upgrade replaces the 1K0 907 530 E (1K0907530E) with a 1K0 907 530 AA (1K0907530AA).

This process works the same for most Volkswagen models.

1K0 907 530 E (1K0907530E)
Revision: 11

1K0 907 530 AA (1K0907530AA)
Revision: H16

Record current installation list and long coding

Take screen shots or make a note of your installation list in controller 19 – Can Gateway using Vagcom/VCDS. This step is critical unless you want to figure out what you had installed prior to the upgrade. Don’t be tempted to copy down the long code unless you are installing the exact same revision of gateway as different revisions have extra features.

Whilst not essential it is worth taking a screen shot of the different screens in the long coding.

Removing and Installing the Gateway

Remove the key from the ignition or disconnect the car’s battery (the battery disconnect is optional but better safe than sorry)

Remove the footwell cover on the drivers side where the gateway is located – Volkswagen Golf footwell cover drivers side – Removal and  Installation.

The gateway can be in two locations on the Golf. One is above the accelerator pedal and the other is above the clutch pedal (if fitted). The clutch pedal location was used for the first year or so of production.

This guide specifically for 2 x power connections and 2 x data connections.

The way this works is you remove the terminal from the housing, join that terminal to the matching terminal and insert the opposite terminal into the housing.

First you need to obtain the connector housings and repair wires.

  • 4 x 191 972 711 (191972711) – Connector Housing

Step 1 – Cut the four repair wires in half, remove the insulation from the ends of all four and twist the exposed wire together. Do the same for the power and CAN bus wire. Join one male and one female repair wire half together (ensure that you join the 2.5mm female to the 2.5mm male) as shown and connect the ground wire to one and redo the step for the power wire.

Step 2 – Solder each of the four repair wire halves and the two power wires from the harness as shown.

vw_skoda_bluetooth_harness_connector_housing_2

Step 3 – Double the harness wire back on top of itself.

vw_skoda_bluetooth_harness_connector_housing_3

Step 4 – Using heat shrink cover each soldered area as shown. Use a smaller length to cover the join and than place a longer length over the top to minimise the chances of any shorts.

Step 5 – Repeat the last part of Step 1 with the 1mm repair wire and the CAN bus cable.

Step 6 – Place a piece of coloured heatshrink on one male/female CAN bus set, ensure that these are connected to the same wire! This allows you to ensure that you have hooked this up correctly later on. Repeat for the power set of cables.

An external diversity box is required [...]]]> Early models of the Mark V had a aerial selection control unit (diversity) under the right front seat to select the strongest signal, in later headunits this function was performed by the headunit itself.  Swapping headunits to or from cars with a diversity unit requires installation or bypassing the diversity unit.

An external diversity box is required for the following models

  • All MFD2 CD versions introduced week 10/2005 until week 45/2005 when the MFD2 DVD version replaced it.

The headunit performs the diversity function on the follow models

  • All MFD2 DVD versions introduced week 22/05 (it is possible that DVD versions fitted between 22/2005 and 25/2005 have the external diversity box but as so few were shipped I haven’t been able to confirm this)

If a car has the MFD2 CD version with the aerial selection control unit (diversity) under the right hand front seat and has a headunit with the diversity function built in installed the aerial selection control unit (diversity) needs to be bypassed which will be covered in detail further down.

On the rear of the headunits there are two antenna connectors.

On cars from week 45/2006 (unverified) the connectors are

HF1 (white) – left aerial module
HF2 (beige) – aerial amplifier

On cars prior to week 45/2006

ZF (white) – to aerial selection control unit
HF (white) – from aerial selection control unit

vw_aerial_selection_control_unit_diversity_1

1 – Transparent connection for FM aerial input signal from aerial selection control unit
2 – Beige connection for FM aerial output signal to aerial selection control unit (diversity)
The aerial input signal from connection 1 is checked in the radio navigation system and the result is sent via connection 2 to the aerial selection control unit. If the aerial signal being received is too weak, this then switches to a different aerial (diversity).

Accessing the aerial selection control unit

Before beginning dismantling work, perform the following steps:
– Switch off ignition and all electrical consumers and remove ignition key.
– Slide front right seat to rearmost position.

– Remove cover under seat in direction of -arrow-.

vw_aerial_selection_control_unit_diversity_2

Release and disconnect connectors -A-.

vw_aerial_selection_control_unit_diversity_3

Remove clips -arrows- and control unit.

vw_aerial_selection_control_unit_diversity_4

Bypassing the aerial selection control unit

The unit under the seat has two connections from the aerials, both are HF and are converted and sent onto the new headunit as a HF/ZF signal.

There are two ways to bypass the diversity box.

Option 1 – bridge connectors

Bridge the connectors internally in the box.

Option 2 – adapter cables

vw_diversity_system_adapter_1The specs on the cables are below and they can be purchased from ebay or ecommerce sites that specialise in Fakra cables.

www.telebox-live.de who sells the following adapters for ~AUD$25 per adapter (2 required)

Antenna extension adapter Fakra (m) Cable 0.1 m
