I once took my Jazz to a local repair garage, due to a similar windshield chip. They repaired it very well, and the center of the chip is still slightly visible, but the star shaped cracks that were around it are not visible at all anymore. The price was around 50€, and my insurance paid for it.
The garage staff recommended that next time when I get a new chip, I should place a piece of transparent tape on the chip, to protect it from water and dirt, until I can take it to a repair garage. Maybe a good idea to do that first.
