How to Clean a Garmin Dash Cam X310 Lens and Windshield Mount

Step-by-step instructions

Step 1: Park, power down and let the device cool

Park completely away from traffic, switch the vehicle off and disconnect the camera’s power cable. Wait for a hot windshield and device to cool before wiping. Do not clean, align or operate menus while driving; Garmin explicitly warns that alignment while driving can cause distraction. Note the current mount position and live-view horizon. If the adhesive mount is loose, treat that as a mounting problem instead of pressing it back with cleaning moisture beneath it.

Step 2: Lift grit from the lens and cover

Inspect the front lens and its polarized cover for grit, fingerprints and film. Use a clean air bulb or soft brush to remove loose particles before the cloth touches the surface. Do not rotate or pry the lens assembly while dusting. Avoid compressed propellant, paper towels and abrasive pads. A pebble of road grit can create a permanent arc across the cover if it is trapped under a circular wiping motion.

Step 3: Wipe the optical surfaces gently

Use a dry lint-free optical cloth first. If residue remains and Garmin’s exact care instructions allow, lightly dampen a clean cloth with water and wring it so no droplets remain. Wipe the lens cover gently, then use a separate clean section on the rear touchscreen. Never spray glass cleaner at the camera or windshield while the device remains in the spray path. Keep ammonia, solvents, oils and coating treatments off the optical surfaces.

Step 4: Clean the housing, cable and mount

Wipe the cool housing and accessible mount with a dry cloth, using controlled moisture only on compatible exterior surfaces. Keep water out of card slots, microphone openings, USB connections and buttons. Inspect the cable for cuts and its connector for dry debris without inserting metal tools. Clean the surrounding windshield separately with the camera protected or removed according to its instructions. Do not soak the adhesive pad or lubricate the mount joint.

Step 5: Dry and restore the exact position

Let every surface and connector dry completely before reconnecting power. Return the camera to its prior orientation and confirm the polarized cover is seated correctly. Do not use heat to dry a device already exposed to windshield temperatures. If the mount moved, open Garmin’s placement and alignment functions while parked. The camera should point straight ahead with the horizon centered as the X310 manual describes.

Step 6: Verify alignment and camera placement

Use the settings for camera placement, vehicle height and alignment. Center the horizon and confirm the selected windshield location matches reality. Garmin notes that advanced driver-assistance features may not work properly when the camera is misaligned. Do not judge alignment solely from the physical case, which may sit at an angle while the lens points correctly. Tighten only user-adjustable joints and replace a failing adhesive system through the proper kit.

Step 7: Test recording and inspect the image

Start the vehicle while stationary and confirm the camera boots, recognizes storage and records. Review a short clip for sharpness, glare, smears and the expected field of view. Check time and status without changing unrelated settings. If haze appears inside the optical assembly, the touchscreen behaves erratically or power disconnects at the mount, stop adding cleaner and use Garmin support. A visibly clean unit still needs a successful recording check.
