windshield cracked

When the friends were going on the gravel road, I cracked the stone glass and I drew the little but the crack was extended by 20 cm (I saw it when I came to the car in the morning) I have to replace the glass immediately. If you have friends changed how many have you helped me I would be very happy ?? there is a rain sensor on the glass ...

Get well, my friend, if you have the supplier of glass, the rain sensor will not work, if you have a casco, you can change it free of charge without damage.

It has no urgency, but the crack grows over time.
It makes sense to state that there is a rain sensor without changing the glass and that you will get a guarantee that it will work after the change.

A scratch on my glass. Because of the wiping. It's been like this since I bought it. Is it possible to repair aceba
