swapping 9w3 with 9w2

[andrep182]

Hi guys,

I have a question regarding swapping the two modules I mentioned in the title. I have a 2010 CC, and I can care less about the phonebook, push to talk and all that stuff, I just want the BT audio to work with my car.

After researching about this topic for awhile, I think I understand what I need to do to make BT audio to work and I just want to confirm that what's in my mind is right.

So, the only thing I need to do would be to purchase a 9W2 module, remove the current 9w3 from my car and swap it with the 9w2 module, then it should be just plug n play right? Also, the only reason that I would need to use VAG COM for this procedure is to configure my 'mic' button to work as mute instead of push to talk, is that correct?

Please let me know if I am missing something within this procedure, thank you in advance!

You have two options:
- downgrade to 9W2
- upgrade to 9W7

The 9W7 module has the same features as the 9W3 but adds A2DP streaming support. You won't be losing any functionality in the process.

I understand that, what i was concerned about was the procedure; I don't have a VAG COM, so if swapping module is a straight up a plug n play thing, and VAG COM will only important if I wanted to set up the button on the steering wheel, I will go ahead and downgrade my module. However, if there's more to it than just swapping the two bluetooth module, I was hoping someone can point it out to me

Have you checked that your OEM BT connector has the audio wires already installed to support either the 9w2 or the 9w7 stereo output (4-wires)?

I would not think so, as the factory installed 9w3 is only mono output (2-wires).

Do you know how to identify the wires? I know there's a bundle of wires connected to the tab which connects to the bluetooth module... But, if what you said is in fact true, then that's a bummer for me =( I really wanted to have this feature, I think it was silly for VW to even create this module (9W3). They should have gone ahead to skip it and make 9w7 after 9w2

Take a look at the upper left corner of this illustration... those are the 4 telephones wires for stereo:



There should be a label with the same illustration on top of your unit.

[andrep182]

You guys both are awesome, thanks for the pointers, I'll check it out

[andrep182]

Bummer! my pin 4 and 5 isn't there, then like M3 said, I got no stereo capabilities.. sucks.

VW sells those wires with the correct pins already crimped.

I think I saw these wires on ebay as well... Do you know any tutorial/instructions on how to replace this cable? I'm a total noob when it comes to cars, so any help/advice is appreciated.

Also, when you said VW did you mean the drivergear site @ the official VW website? because I did not find it there... please bare with me, I'm trying to learn asap haha

VW = dealer

Contact Bud at CheckeredFlag VW, he's a vendor here. He will get you those wires.

You will not replace the cable, you will add those two missing wires to it. The pin assignments for that BT module connector are somewhere in this forum, so you will know which pin in which slot goes where in specific.

I also have this problem. I have a 2010 CC with a RCD510 and I upgraded the 9w3 to a 9w7 just for A2DP only to find out that these 2 wire are missing. Now everything works but I only get music on the right side of the car.

I know where the two wires go on the bluetooth unit but have no idea where they go on the RCD510 dose anyone here know? Also I have called many VW dealers none can give me just the wire harness with the two missing wires so I'm trying to add them myself but I also need to know what end to put on the wires so they would connect and lock into the plastic connectors.

Any help would be greatly appreciated

Look at the diagram M3Tech posted above. They'd connect to pins 11 and 5 on the little telephone connector on the radio's quadralock connector.

Thanks, I missed that when I looked at the diagram. The only thing I'm missing now is what type of connectors goes on the ends of the wires that then get inserted into the quadralock connector.

Thank for the info M3Tech, now yet another problem no one seems to have them in stock Dose anyone know where I can buy 963726-1 terminal in the US?

You can request samples from Tyco; sometimes they send 4-6. The problem with that contact is that it is sold in quantities of 500-50000.

Contact Bud at Checkered Flag VW: http://forums.vwvortex.com/member.ph...heckeredFlagVW

He should be able to get you the VW OEM version of that Tyco connector, including the wire already crimped to it. The P/N should be part of the repair section of the Quadralock sub connectors (12-pin each), so either the parts or the service department should be able to find it.

[andrep182]

Hmm I never went this far to find out where the quadralock terminal is located, I guess I'll take a look at it tonight ... Somebody is selling 9w2 module for cheap, I need to figure this out asap

[dcjenkins]

I just wanted to pop in and say thanks for all the instructions. I am a few days away from having to do this myself, so I will definitely be back to comb through these threads. I know to you guys who can do this in your sleep it may get monotonous to relay this information, but for us noobs it is greatly appreciated!

[dcjenkins]

If you decide to sell your 9w3 unit please let me know, I'm looking to purchase one. Thanks.

Just sent a PM.

I second this, you guys rock!

[lionmilk]

I have also a 9w3 unit available if anybody's interested! Just got out from my CC that has 567 miles on it haha.

[andrep182]

man 9w3 is such a fail product, lol

[andrep182]

If anyone is wondering on how to open up the head unit, I found a thread that shows it step by step

I finally got A2DP working I would like to thank everyone for all the help, I don't think I could have done it with out you guys. A special thanks to Bud at CheckeredFlag VW he did what no other VW dealer would and got me the part number I needed.

For those of you still trying to find out how to add the missing wires to make A2DP work. This is the part number you would need (Thanks to Bud) 000979010E or 000979010EA. This is nothing more then a wire with 2 terminals so to get the 4 terminals needed you will need two of them.

[dcjenkins]

Actually, thanks to me. And then thanks to Bud.

Who do you think he calls when he has questions? Haha.

Haha. Indeed, thanks to dcdubbin202! I just installed my 9W7 and it was beyond easy, I couldn't believe it. And, the push to talk on the steering wheel works with no problems! The voice recognition is cool!!

Now all I need are the wires from bud to get stereo for my A2DP. I've PM'd him -- if there is a better way to contact him, please let me know.


Many Thanks,
Dave

mdraco, did you have to connect these two new sets of wires to your RNS-510 directly or is there a more convenient area to connect?

Also, just to confirm, this is all you needed to convert to stereo from mono, are these two sets of wires?

Thanks.

I connected them to RNS-510 using the phone connector, on my radio it was the only connector that had two wires. I just unplug it and inserted the wires then plug it back into the RNS-510. I didn't unplug any of the other connections so the radio never lost power.

Yes, the only thing I did was add the two wires nothing else.

[Random One]

Has anyone got the stereo bluetooth to work with the RCD510 ?
I got the 9w7 installed with no issues and dcdubbin202 pointed me to the telephone pin out. I made the two wires for the connection and placed them in pins 4 and 5 on the bluetooth, then 5 and 11 on the head unit. I don't get stereo,. I even jumped the outputs from the right to the 5 and 11 left just to see if I could get sound out of it and it does not work.
I am beginning to think that the standard RCD is crippled.

Any help is appreciated.

You'll have to excuse me if I'm asking the painfully obvious, I'm just attempting to properly visualize this before I start. Could you please confirm or clarify?

1) So, you had to remove your RNS-510 from the dash, but not disconnect it, in order to gain access to the phone connector, which I assume is on the back of it?

2) With your two new set of wires, do you have to feed them under the carpet and behind the dash to the RNS-510? And then into the BT connector at pins 4 and 5?

Thanks!

I removed the head unit since it was easier to get me hands back there. The wires can be fed down the back and then to the passenger side where you remove the trim piece you have access to the carpet. I just forced my hand in the area that the 9w7 sits, and reached diagonal towards the side. Then pushed the wires down in with other hand. Very easy since they are thin wires, just do not pull the wires because they can break based on the gage of your wire.

[Random One]

Sorry! Pins are different on the RCD. Try 11 and 12...

1 – *Microphone input, negative
2 – *AUX output, audio, right
3 – *AUX output, common signal earth
4 – *Microphone output, negative
5 – *Telephone audio input signal left, negative
6 – *Telephone audio input signal right, negative
7 – *Microphone input, positive
8 – *AUX output, audio, left
9 – *Microphone output, positive
10 – *Telephone mute (mute switch for radio)
11 – *Telephone audio input signal left, positive
12 – *Telephone audio input signal right, positive

I may have been looking at this to long and can not just see what is in front of me, but I found that is the same as your pin outs. There is only 5 male pins in the headunit for that connector. R+/_ is the only one that was connected on pins 6 and 12. is it possible that the mute pin is not 10 and really 5 ? so then I go 11 and 10 ?
I really do not want to crack open the case on the RCD to trace the circuits.
I will make new cables and double check tomorrow.

Anyone want to sell me a RNS-510 for cheap then I can quit worrying about this.

thanks for all the help

1) Yes I removed the radio from the dash, there's enough slack in the wires that you don't need to disconnect the radio. All the connections are on the back but I only disconnected the phone it was the only one with two wires.

2) Yes I had to feed the wires under the carpet and up the dash. On the BT I connected pins 4 and 5.

Yes, this is painful dude.

You should go to a professional, you are going to mess something up.

When you did step 2, did you get stereo A2DP ? I am hearing that I might need to code the RCD to get this to work.
