'Rider, have you considered going for the alientech module thats fires the windows up or down on the standard fob?
Its an affordable mod at ?50, and is incredibly useful (as well as quite flash!)
It does:
Roll windows up
Roll windows down
Vent 1"
Vent 2"
Vent3"
it also allows you to put the windows up (or down) with the key in the lock, but you don't have to stand there holding it. Just twist and go!
It took an hour to fit, and I wouldn't be without it!
