Hello! Santa is bringing an early Christmas present for my '14 Sierra 1500 SLT this weekend, a VIOFA dash cam. I was thinking I'd tuck the front camera in behind my rear view mirror, drivers side of mirror mount, so it would be within reach yet not obstruct my visibility, but have noticed there appears to be some kind of sensor on that side on the mirror (sensor is facing forward, ie back side of mirror). Anyone have any idea what that sensor is and if it would cause in issue to have the dash cam there? Thanks in advance for any thoughts.
