Not all functions work on Passat Wagon B6

If you are using this adapter in a 2006 to 2010 Passat Wagon the RAP does not work. I spoke to the Axxess rep and he said that there is a software glitch between the adapter and the Passat. Axxess will have to release a new model to fix this issue. Also, for the Pioneer DVD head units that need the parking break on/off/on signal, the adapter will randomly work.

Best Purchase

The wiring harness may look like a head scratching stressful mess but don't worry, its easier than it looks. Anyone can set up this radio. The directions that it came with a whole lot easier. The product was very good in quality.

works good

I'm pleased enough with it. The instructions were a little lacking, but what became apparent after looking at it for a bit was there are 2 harnesses which can plug into the box, and to me I used the one that was wired to the stereo's power wires and it worked. Also it needs to be programmed to the car by turning the key on for 30 secs to a minute with all doors closed.

The retained power feature did not work in my 2006 Jetta. It is supposed to leave the radio on after you remove key until the door is opened, but mine just turns off with the key. Not a big deal really, it'd be nice if it worked though.

Monsoon compatible

Was confused on all the different harness adapters out there. This one even says non amplified, but it is THE one to use if you have a Mk4 jetta/golf (bora) with amplified monsoon system.

Could be better

Instructions that are included could be a little confusing to someone who has never installed a stereo and not a lot of markings on on the harness to figure out what wires are for what
