Does installing a comma device require permanent modifications to the car?
Installing a comma device does not require any permanent modifications to your car. With the car harness, most car trims remain in place.
How do I mount my comma device?
Watch our Mounting Guide. First, figure out where on the windshield you would like to mount the device. We recommend it be centered on the windshield below the trim. Be sure to leave enough room to remove the trim in the future. Clean the windshield before mounting with the included alcohol wipe. Remove adhesive and hold mount in place with light pressure for 10 seconds. Remove the comma device and press firmly on the mount. Let the adhesive cure for 48 hours.
Before placing the device on your windshield, check the state and local laws and ordinances where you drive. Some state laws prohibit or restrict the placement of objects on the windshield of a motor vehicle. IT IS THE USER'S RESPONSIBILITY TO MOUNT THE DEVICE IN COMPLIANCE WITH ALL APPLICABLE LAWS AND ORDINANCES. Always mount your device in a location that does not obstruct the driver's view of the road. comma does not assume any responsibility for any fines, penalties, or damages that may be incurred as a result of any state or local law or ordinance relating to the use of your comma device.
Note: In California, a system with driver monitoring can be mounted on the top center of windshield.
Will installing a comma device void my warranty?
From the FTC website: "Simply using an aftermarket or recycled part does not void your warranty. The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket or recycled part."
Will my insurance cover my car with a comma device installed?
Contact your insurance provider directly; insurance coverage is between the user and their insurance provider. comma hardware users have been able to get coverage and discuss this on reddit here.
Insurance companies are beginning to understand the safety benefits of ADAS and LKAS systems like openpilot and we have not heard of any providers rejecting coverage to comma hardware users.
How long will my device have software support?
Although there's no official support for any software, it is comma's policy to continue providing software updates to hardware for 1 year after it is the latest generation sold.
