Word of warning, the RF Receiver doesn't have any part number stamped on it anywhere.....so be very careful! Ask for a copy of the receipt of when and where they bought it.
If no receipt, DO NOT BUY IT! It's far better advice to go and buy it from an Independent LR garage or even dare I say from Land Rover themselves!
how are you supposed to check which version you have?-
incidently, I don't have he RF problems as some of you have mentioned ( I do have CCTV and WIFI ) but would like to know which revision of the RF receiver I have.
