Removing your mount can be quite tricky, but it’s certainly not impossible. View the manual for a detailed explanation. Heat the mount/3M adhesive with a hair dryer and use a credit card to release the corners of the 3M adhesive. You can then remove the mount from the helmet by twisting the mount. The 3M adhesive won’t damage your helmet if you remove it the correct way. It may leave some residu, but is easily cleanable with an alcohol pad.
