hi what would I need to fit the rcn210 unit to my 57 plate ed30 , my car has different controls to the golf in the youtube clip
cheers
You need the
Quadlock to ISO adapter with CAN wires and the aerial FAKRA adapter. The extra CAN wires are used to tap power from the Climatronic which has similar wiring to the semi-auto system in the YouTube clip (orange-green and orange-brown wires), you need to do this to get the backlighting and bluetooth working. To feed the two wires to the adapter use
these instructions on where to place them in.
It can be a bit fiddly so be patient, and once connected you shouldn't need to worry about battery drain (the RCN210 worked fine with my ancient Revision E gateway and had no draining issues under my experience). If the idea of tapping wires puts you off then you may as well consider getting the RCD 330 for a little bit more which is plug and play with the existing cable though you will need a Canbus upgrade if its before a Revision K.
Also to mention that if you have a MFSW then you may find that this will no longer work with the new stereo, you need to upgrade the steering module to at least a "CH" revision to regain the audio controls back.
