I installed my RCD330 the other day, latest E part number with 565 hardware and Y510, C210 software. Now I can see why some people think it works fine with Dynaudio and others realize it doesn't 100%. It depends on how loud you turn it up. It works fine with the volume anywhere below half, once you go towards 2/3 or 3/4 it starts to distort and all the way up is just a wall of distorted noise unlike the stock RNS315.
After taking some voltage measurements from the speaker outs I was right in my thinking. The RNS315 only puts out a 4V max from the speakers when all the way up. The RCD330 being made for cars without external amps isn't limited on it's speaker output and will spike above 6V when all the way up. That's why at around that 2/3-3/4 volume it starts to distort since it's surpassing the 4V the Dynaudio amp is expecting from the headunit.
Since you can't Vagcom code the voltage down on the RCD330 like you can the other RNS units since it never came in a car with an amp you have to drop the voltage with hardware, essentially treating it like any aftermarket headunit that also can't be coded. I have what should be the answer to this problem on the way and once I can confirm it works I'll post more info. I don't want anyone who cares about this to spend money on something until I test it.
It also, as expected, doesn't show the fader, just balance which is due to coding. Once I get my hardware speaker level fix I'll also try some alternate coding since apparently coding it for a Skoda amp will then show the fader.
Beyond that, at 50% volume and lower the RCD330 is a real nice upgrade to the very small screen, very dated feeling RNS315. I much prefer using Android Auto and Google maps to the old RNS315.
As for any other things to note, mine does have the odd quirk that others have mentioned where after using Google assistant the volume will drop on the music you were listening to, but not every time and only if it's Android Auto music, not SD card or radio. I can live with that little quirk since it takes an extra second or two to raise the volume back up.
An update regarding the Dynaudio issue, sadly i've had no succes with the alpine adapter.
First of all the adapter had DIN connections, which I changed out for 8 pin quadlock connections. Then I added in the adapter in the quadlock extending the original 8 pin through the adapter.
However, no succes, the sound still distorts 60%+ volume and there is still static noise from the tweeters
The volume of the sound does seem lower with the adapter though.
Although I do have a Scirocco it's the same Dynaudio system.
Anyone have any clue what the difference is between the 187E version with Y510 FW and the 187B version with 5314 FW? Or even the 5515 FW?
I recently contacted a reviewer who bought the 5515 FW and is reporting no bugs unlike what I've read here from posts a few months ago.

Finally got my OEM-replica backup camera installed and working. If anyone needs help installing one, feel free to send me a PM.
