Do You Need to Remove a Dash Cam Before Windshield Replacement?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
Anything bonded to the old windshield leaves with the glass, so unplug your dash cam and peel off the mount pad before the replacement. Save the pad so you can refit the camera afterward. Wait until the safe drive-away period has passed before sticking it back on, and keep it clear of the camera and sensor area behind the mirror.
What to do with the dash cam before the job
A few minutes of prep keeps the camera and its mount from riding into the trash with the old glass.
- 1
Unplug the camera
Disconnect the power cable at the camera or the 12-volt socket, and tuck the wire out of the way so it does not snag during the replacement.
- 2
Peel off the mount pad
Lift the adhesive pad from the glass with steady pressure. A little heat from a hair dryer softens the adhesive, but never use a knife or scraper that could scratch the glass.
- 3
Save the pad and cable
Keep the pad, cable, and any trim clips together in the car. Reusing the same pad saves you sourcing a new one, and the cable routing stays where you like it.

Tell the technician
Mention the camera when you book, so the technician knows the glass is clear of hardware before the cut-out and can plan around the camera bracket behind the mirror.
Why the camera comes off with the glass
A dash cam mounts to the windshield with an adhesive pad or a suction cup, and the glass beneath it is the part being replaced. When the technician cuts the old urethane bead and lifts the glass out, anything stuck to it comes along. A camera left in place would be torn loose, its cable strained, and the pad destroyed.
The forward camera that feeds the driver-assist systems is a different matter entirely. That camera sits in a bracket bonded to the glass, and a replacement done with glass matched to the VIN carries the bracket across. The recalibration that follows is part of the same job. Your dash cam is your own device, so removing and refitting it is on you.
Wait for the safe drive-away before re-mounting
Fresh urethane needs time to bond before the glass takes vibration or load. The work itself runs about 45 to 75 minutes, and a 30-minute safe drive-away follows so the bond can set. Hold off on pressing a new adhesive pad onto the glass until that period has passed, and ask the technician where the bond is firmest if you are unsure.
Where the dash cam can and cannot go
- High and tight against the rearview mirror
- A compact camera tucks behind the mirror and out of your sight line, but it must not sit in front of the forward camera or the rain-and-light sensor housing.
- Low and centered on the glass
- The lower center of the windshield is usually clear of sensors, though the cable run is longer and more visible.
- Anywhere in the driver’s direct view
- Off limits. Nothing may block the patch of glass you drive through, and the camera and sensor area behind the mirror stays clear.
More questions about dash cams and replacement
Do I need to remove the dash cam before a windshield replacement?
Yes. Anything stuck to the old glass comes off with it, so unplug the camera and peel off the mount pad beforehand. Save the pad and cable so you can refit the camera once the safe drive-away period has passed.
Can the glass shop reinstall my dash cam?
The shop focuses on the glass, the urethane bond, and the camera bracket behind the mirror. Refitting a personal dash cam is usually yours to do, though the technician can tell you where the urethane is firm and which area to avoid.
Will a new windshield affect my dash cam?
Only the mount location changes. The camera itself is unaffected, and once it is reattached with a fresh pad clear of the sensor area, it records exactly as before.
