So... do I understand this right.... if I don't get the harness/PAC C2R thing, then I have to run the wires and do the headlight 12v power deal that you show in the install guide to keep the same functions I have now? (no navi, no steering wheel control. Basic B5.5 FWD Passat)

But if I do get the PAC C2R thing, then I can just plug that and the harness stuff in, no need to run or do custom wiring, and it keeps all the factory functions/power setup.?

I have a question that someone may be able to help me with

I am trying to install a Soundstream 8300 flip out dvd headunit. I followed this thread in perfection. I've double checked, then checked it again after that.

My problem is (I believe) not getting enough power to the factory monsoon amp. The head unit powers on fine but there is no sound unless I turn the volume up to max, then it blasts.

Also, when my car is running it works better than before, allowing me to hear music without it maxed out, but when I turn my headlights on all the sound turns off...

I'm so lost! I've checked all connections and they are proper.

Any suggestions? I'm hoping it's not the head unit failing.

There's something wrong with your HU or your install, it's as simple as that. The install is exactly the same whether you have Monsoon or not so the amp "not getting enough power" isn't the the issue.

Did you use the HU's speaker outputs or it's RCA outputs? How, specifically, did you get power for the HU? What adapter did you use?

I'm not sure what is going on with it, i used the speaker outputs and wired it up like I would on any other cd player.

I tapped into the 75x bolt for the switched.

The head unit powers on normally. When my car is on, I have audio but it sounds horrible. When I mute, you can hear constant static.

When my car is off and I try to use it, no sound...

I've been told by 3 different people that the PAC CR2-VW2 interface would fix my problems. Is that true?

And if it helps, I tested the this head unit in my brothers car and it worked fine. So it's not the cd player.

Ooooookay... This thread helped quite a bit. However, I need some serious help... I am absolutely clueless when it comes to electronics, so I am wondering what I have gotten myself into here...

Anyway, I have a B5.5 1.8t, that came with the single DIN monsoon system, which promptly took a $hit and started to drain my battery, so I had the garage pull it. Ordered me up a Kenwood 248U from Crutchfield, and got the PAC harness with it. So, I go out to take a look at the plugs, and there are three of them, a black one, a brown one and a tricolored one as can be seen here . As you can see here , there is no "lock mechanism" (EDIT: It is the lock bar mentioned in the original post, was this exclusive to the double DIN units?) thing that is required in order for the PAC unit to hold the plugs together... WTF? Is this normal?

Also, I noticed that in the actual PAC unit (see this ), the first two columns on the left match one of the connectors, but the next two appear to be missing a few prongs... After reading this, is this to prevent that K-line from screwing up OBD scanners? Or is this plug effed up? Also, that only provides prongs for the black and brown connector, so what happens to the tricolored plug? Do I just leave that unplugged (along with all the other steering wheel ends on the PAC connector)?

On top of all that, if someone could explain to me where that CAN-BUS box thing plugs into and what on earth it does, that would be freaking awesome!

Thanks for the patience and any help you can throw my way! :)

I have a 2004 2.8L V6 engine Passat (Auto trans). The car has a factory 2 din monsoon radio that's not working anymore. I've tried to pull it out but it does not come out. Went to a car audio specialist but they couldn't get it out too. It seems that it's probably jammed, and I have to remove the whole dash to pull it off. Is there any D.I.Y. for that, or anyone that had the same issue here? Thanks!

Hello pedromfc,

The first question I would ask you is, what type of tools are using to try and remove your head unit? If you did not buy the VW removal tools, have you made your own? If you did not read the entire thread, go way back to the first page. There are good instructions on how to make and use your own removal tools. Sometimes things just get stuck, but if you fully disengage the four locks and apply even pulling (or prying) forces to the four corners of the HU, you should be able to wiggle the unit out. You might need to get a friend to help. If it is already busted then you do not need to worry about damaging it on the way out;) but be careful not destroy the cage inside the dash. I chose to pull my stock HU and it was difficult for me too, but it came out all the same. Re-read the first page at least and make sure you understand what you need to do (depressing the four spring tabs) in order to get it out. Attention, patience and perseverance will get you along way.

Yes, I read the entire thread beforehand. Went to 2 auto stereo specialists, and also tried myself very carefully, with VW tools, for several hours, and still couldn't get it out. We think that it's jammed. Still would like to know how to remove the dash so I can take the radio out. Anyone? Thanks!

Does anyone know and can explain how the three HU-Factory connectors (SWI-CAN, SWI-JACK, and C2R-VW2.....one for the HU 2 for steering wheel controls) are supposed to come together? Trying to figure this out and having a rather hard time with it.

I just installed a JVC HU using only the C2R-VW2 module in my 2006 Passat. Very easy. No other wiring necassary. I don't have steering wheel controls but it the C2R-VW2 has the module to simply plug into the SWI-JACK. That should be all it takes to keep everything as OE as you can get. I can't believe I waited two months to do this.

I have a 2002 V6 wagon with the Single DIN cassette player. If I order the Metra harness, do I just leave the Blue wire with White Stripe (Amp Turn On) alone? I've gathered that if I hook that up to anything I'll have some serious issues with the VAG-COM. It's a Monsoon system, also.

Just to clarify, if I am installing an amp, and my radio does not have both a Remote, and power antenna, I could tap #30 with both. Correct?

If your aftermarket radio does not have a power antenna, or you don't think it will provide enough power. You can do what I did. Follow the guide at the12volt (a very very resourceful site if you do many installs).

I used my remote turn on wire and tapped a relay, so I can just plug and play amps, power antennas, and anything I may add that needs to be switched with the radio in the future.

Special Applications with SPDT Relays, Diagrams (special application wiring - more devices to your remote turn on wire)



87 - Tap the yellow wire on the harness
85 - Tap the black wire on the harness
86 - Radio Remote
30 - Your new high power remote wire Hook your power ant. wire here (This should take care of any reception problems I keep hearing about)

Just get a headlight relay at napa (load capacity does not matter -- the battery wire to your radio and your after market radio - if of decent quality - is already fused)

yes. or you could tap into the distribution block under the dash labeled 78X, iirc.
