Feeling a bit pleased with myself here :D as I've manged to fit Cruise Control to my 04 TD5 Automatic. Land Rover Dealer quoted about £300 but I bought the bits from Discoparts for £58 delivered, and it took less than an hour to fit. Works a treat.
Thanks to Paul for submitting his article about it
