The Skoda Superb talks of a heated windscreen as an option.
And very good it is too
FYI, heatedwindscreens.com (the 1st supplier contacted) is owned and run by Ricky Evans, who developed these
many years ago for use in rally cars, I know of several people who have used his screen without any bother, Ricky is also a top bloke! (and can certainly 'pedal' a FWD rally car
)
The extra £13 for the sensor mount is because these are bonded onto the screen like your OE one.
Finally Ricky also owns Tamworth Mobile Windscreens so he would be the ideal person IMO to fit the screen for you and would remove the possability of the screen getting broken 'in transit' by the courier company
The wiring looms on the OE screens are bonded to the bottom corners of the screen
