I've just bought a modified RS Monitor on Ebay for my Mk3, fitted it and it works perfectly. (Cup car, monitor not optioned from new, 2011 car) Seller is going to list some more so giving everyone the heads up so you can keep an eye on his listings for when they go back on. I'm chuffed with it in all honesty, easiest upgrade I've done https://www.ebay.co.uk/itm/235386777219
