I have just picked up a Rover 75 Diesel today. Strangely I found a photo of the actual car from a whatcar magazine.
http://www.whatcar.com/rover/75/saloon/used-review/ it's in Twilight.
It has a Webasto fitted and has the timer in the centre console. I looked at the receiver in the passenger footwell fuse box and there is a T80 receiver. Looking around those remotes seem impossible to find. Can I use a T90 or T91R remote or do I need to change the receiver box to the later matching T90 or T91R
