I bought a Golf PC back in 2010 but could never find any one who knew how to instal it. it has the same fittings as the standard head unit but also a lot of other connections see the attached spec sheet. they had videos on how to fitt it but I'm not confident playing around with the electronics. I'm not sure if its worth fitting now or selling it. has any one ever fitted one of these and is it to do?Replacing RNS 510 with RCD 330+-car-pc-jpg
