You buy the toureg TV tuner usually from German eBay say 800 quid (anyone reading this in the future, the only tv that will work in europe is the 7L6 919 148A if you see another tuner really cheap do not buy it as it will not be a europe model, fyi the cost from VW for it is over 2000 quid) , you buy the loom for the TV tuner from kaufatec say 8o euro delivered , you buy the rear window aerials and possible roof aerial from TPS including aerial leads approx price say 200, if you have the rvc you have to change the camera from rgb camera to composite video VW camera and run it through TV tuner approx 180 quid
