Ahhh yes the Helix - AKA the VW dealer sold Plug and Play sound system.
I did ask about this at my dealer when I got my car, they said fitting was £150 quid to which i said "but surely its just a simple job" and they said "no".
So, no, not exactly P&P
I thought initially that like DynAudio you have a sub in the spare, but then I found out the P&P one means you have to loose the spare.
Ok, so its been a while since I've had a puncture, but I can guarantee the second I fitted that...
I'll wait. If I do get another Mk7 next year, I'll spec DynAudio for sure.
