It is twice as bright as standard mirrors, and the LCD display sensor adjusts the screen's brightness to the ambient light so it's easier to see, brighter when it's light outside and dimmer when it's dark out. There are also adjustable guidelines for added safety, which can be adjusted using the included remote.

  1. I recently bought a 2015 YukonXL Denali (bought June 2018) and now I am experiencing this problem. GM’s PIT and free replacement ended August 2017 and I am unable to determine if this vehicle was previously repaired. I do not believe GM should be free from this obvious engineering flaw but the local dealer is adament that I pay for the replacement of the antenna. I am pretty disappointed by their position.
