T5.2 (2011+) OEM retrofits: RNS510 nav, 9W7 bluetooth, RVC, MFSW

[YellowLemon]

See below in this thread for information on these additions to my T5.2 Comfortline Multivan:

• RNS510 navigation radio
• 9W7 bluetooth kit and microphone mounting
• RVC rear view camera
• Steering wheel with DSG paddles, multifunction buttons, and flat bottom from mk6 Golf R
• Extra 12V sockets on top of the centre trim (like in the new MY2015 T5.2) and in the glovebox (constant on)
• Add light to glovebox. VW DIDN'T PUT A LIGHT IN THERE?!? What a joke.
• LED bright number plate lights (from R-dash)
• Rear fog lights rewired as backup brake lights (2x diodes on each tail light assembly)

I've started separate threads for these mods:

• Mirror electric folding retrofit
• Mirror puddle lights and turn signals/indicators
• DRL daytime LED lights in front bumper
• Front door warning and puddle lights

Still to do:

• Put LED strip in rear reflectors as brake lights (saw this on a UK forum, looked pretty cool)
  Link: White van man T5 Transporter - Readers Rides.... - Edition 38 Forums - this is still pending.
  Plenty of parts on eBay to have a go at adding the LED strips, have a look for part numbers 7E0945106/7E0945105 (R/L)

RNS510
Great info in the forum sticky: T5.2 OEM Radio Options - fitted post delivery
To get to the 4 screws holding the RNS510, first unclip the trim at the TOP of the centre dash, by pulling vertically up, and this reveals two torx screws holding on the front fascia of the centre portion of the dash.

9W7 BLUETOOTH MODULE

1. The stock location for the bluetooth black box in the T5.2 Transporter/Multivan is under the driver seat. (thanks IN2VWS) However carsystems.pl support says they prefer installing it behind the dash, saying there is plenty of room.

2. The A-pillar is held on with clips but you have to remove the unscrew the grab handle first (after removing the handle cover).
   
   
3. The microphone usually has a separate bracket in the T5, part number 7H5 857 155. Although the centre overhead light console also has a spot for the microphone - see posts below for how to fit.
   

RVC REAR VIEW CAMERA

Best path for the wiring: Up in the roof liner and then down the A-pillar sounds easier than along the floor on the sides (which needs unclipping of the sliding door steps/sills, what a pain!). See post below for update on the RVC install!


GOLF mk6 R - FLAT BOTTOM MFSW MULTIFUNCTION STEERING WHEEL

Since this Multivan has no buttons whatsoever, I will need to run two wires to the steering wheel slip-ring/clockspring: one for 12V power and one to the BCM for LIN-bus connection to the little module inside the steering wheel. See post below for instructions.
