RNS510 and 9W7 Bluetooth in new Polo 6R

[sVWatt]

Most likely the Spanish harness will work fine as-is, however it has the microphone connection bridged between the RNS510 and 9W7 Bluetooth. The RNS510 has a separate microphone pass-thru, so I changed the pins as detailed here:

The Volkswagen Club of South Africa - View topic - Golf VI GTI RNS 510 and 9WZ Bluetooth Install - Long Post

and

Volkswagen RNS 510 Microphone Connection for voice control | my-gti.com (Option B)

I also cut the microphone wire to make installing easier, and then rejoined it at the centre console to the piggyback harness (see point 4 below)

3) Removing the old RCD310 system
Follow the excellent instructions by GraveDilute, this guy is awesome.

Particularly note the noob hint to remove any CD's first!

HOW TO: Install a Bluetooth Hands Free with Mic.

4) Wiring the microphone
After removing the RCD310 I wired the microphone, starting at the cabin light at the top. This all clips out very easily with minimal force. Note there is a piece of black plastic where the microphone belongs which has to be gently clipped out with a long screwdriver.
You don't have to unscrew the sunvisor, mirror light or roof handle at all.
Just unclip the driver side A-pillar trim buy pulling firmly starting at the top. There is no Torx screw under the Airbag logo, it's all just clips. I did this with no damage. In fact, there is not even an Airbag under the A-pillar trim I could see.

Here is a guide for the Golf, again note it is much easier in Polo because there is no Torx screw:
Volkswagen Golf upper A-pillar trim

Use a long rigid wire (like solid copper electrical wire) to push the microphone cable from the dome light to where you unclipped the A-pillar trim. No need to remove the headliner at all as there is plenty of space at the front near where the headliner meets the windshield.

Route the wire down the A-pillar, and unclip the trim at the driver's side of the dash, and again use the rigid solid copper electrical wire to push the microphone wire to the centre console where the radio was.

5) Install RNS510 radio
Again just follow GraveDilute's photo instructions above. I put the GPS above the air vents too, perfect spot for it. Removing the air vents required some jiggling, but it was fine. I didn't break any trim when doing this. Also remove the aircon control unit (2 screws from below, above where the cupholders are), and when you are inserting the RNS510 into the slot, you can help by pulling the extra cables away from behind the RNS510 using a hand in the aircon controller slot.

Took two hours...removed the RNS, heater controls, stereo 'cage', drivers side end of dash, side pillar and roof lights.
Removed older blue tooth unit, and installed latest VW one. Noting the need to cut the red and black wires which loop the mic in / mic out on the RNS wiring harness, as I wanted voice control which means wiring the mic into the RNS and then wiring the RNS mic out into the Bluetooth.

The most troublesome parts of the job were removing the side pillar to run the mic cable .... It's very tuff and should be pulled in a direction parallel to the front window...ie accross the dash, NOT towards the drivers seat.

The 9W7 comes with three lugs which stick out and make squeezing it and a metre of extra harness cable back into the dash pretty tight, so i cut the soft plastic lugs off and that gave me some room to move things around in there

Plugged climate control wiring back in and RNS wires to do a quick test before putting the units back, tightening the torx screws and putting the trim back....all good.

2 hours, couple of cuts (minor) on my fingers and hands.

My tips - 1. read the forum, 2. buy those blue trim removal tools so you don't leave marks on the dash trim when taking them off, and 3. wrap the Bluetooth in rubber or foam around the edges so there are no plastic squeaks when you sit it inside the dash.

Mate,

Glad to hear it all worked out.
You forgot to mention that you saved a stack of cash doing it yourself, you learnt something new and now you can spend the money you saved on something else shweet for your ride.

Ah yes that's a really good tip actually. The other thing I did was shorten that ridiculously long harness by cutting and re-soldering the wires (they are individually colour coded). It fits fine when it is long, but I find it neater this way Enjoy your new bluetooth!! I know I do.

I am - I hate cluter - so having no visible 'after market' mike glued to the window makes me smile, and the fast start up / connect, and proper sync to my iphone 4 contacts makes me

Next goodies- got to be those DRLs

Hi,

What size HDD is in that particular rev D unit you bought and what is the production date of it?

Cheers

[Transporter]

To my knowledge they're all GB.

[YellowLemon]

Hi - my rev D unit has a ~30GB hard drive and production date is March 2011.

So I just finished doing this conversion (RCD510 to RNS510 + 9W7 Bluetooth)
The RNS works great. But I cant pair with the bluetooth. When i turn on the ignition and search for a bluetooth device on my phone (and the mrs phone) it doesn't find the Polo's 9W7.
Its almost like the 9W7 module isnt there.
The kit I bought came with a secondary wiring harness that seemed to go between the factory large plug (back of the RCD) and the RNS & 9W7 module. I double checked the connections and everything is plugged in (maybe an issue??) THe large square plug, single blue plug and dual white plug into the RNS, the 9w7 plugs are in nicely also.

Any suggestions??

[YellowLemon]

What does the screen say when you press the phone button? No phone found or no module found? Try resetting the RNS510 by holding both arrow keys and the star key for 5 seconds

[BENN0]

Nothing comes up on the screens when I press or hold the phone button.
Resetting didn't help either. Im guessing there is a wiring issue. It seems like the RNS doest see the 9W7 module at all.

YellowLemon, Gavs, and others
Just had this very BT unit (from Spain) installed and paired with RCD510 in GTI.
After some initial hickups (couldn't find my iPhone) finally did and all ok.
However, steering control buttons and MFI not working...
Am I correct that this is a programming thing, and can be done by dealer or anyone with VagCom tool?
If so, what is required, bearing in mind that I am in Far North Queensland and there is not exactly a lot of choice of places to go?
Would love the steering buttons to work.
BTW, install of BT unit cost me $165, with unit installed behind glovebox and mic in its proper place above centre light. Sounds great through the stereo too, although phone ring made me jump from my seat!
any help greatly appreciated.
thanks

Yes, for the steering wheel buttons to work you will need to have this function activated either by a dealership or someone with a VagCom unit through teh control module for the steering wheel.
