Hi, I'm interested in getting a Golf GTI or R and was looking for the Dynaudio upgrade. Finding it hard locating one with the Dynaudio up for sale on Autotrader and Ebay so contacted my local dealer to check if they had any. He said they don't have any with Dynaudio but you can get a Plug and Play system to add to any MK7 Golf. My question is, which audio system is better? He quoted me £465 to add it onto any Mk7 Golf which isn't much less than the Dynaudio option costs. I'm coming from an Audi A3 with Bose Sound System.
