I just had the windshield replaced on my 2015 CX 5 with tech package. Safelite replaced the glass and after some discussion determined that I didn't need to recalibrate the sensor (laser) (and save $300)for the collision avoidance device. This device is built in or directly behind the windshield. I have some recollection where Mazda required re-calibration with new glass. Can anyone confirm one way or the other? Thanks
