I have a split in my screen and it needs replacing, it is a heated screen and it appears to be bonded into place (you can take the rubber seal off and see black glue), is this a diy job or special job for a windscreen fitter?

if its a diy job what will i need and what will a second hand screen set me back

regards

console

ps if its a job for a fitter who is the cheapest home fitter (car is off road)
