I have fitted the powerfolds from smc to my ZTT. I could not get hold of a switch pack so bought the ign activated auto switch from Eurorover.
Now it is fitted I am prefer this option. When you start the car the mirrors fold out and fold back when you park.
There is an overide switch if you want to leave them folded out. So do not be put off over the lack of oem switches fit the Eurorover option instead.
Had Rover designed it this way you not want a manually operated switch which you would most likely forget to press anyway!!
