'cuz it takes a lot to get HUD ... at least you'll need a HUD specific front glass (among other things) otherwise the HUD will not be properly reflected using std windshield.

I have the same thing - th button in the corner, but I don't have L7. If it's a sensor what's it for? My mirror has rain and light sensors as well as the alarm sensor, so what the heck is that one for?

I think it's a light angle sensor ... when the light in auto sometime it'll turn on even it's not dark ... the car maybe smart enough to know when to turn on the light around dawn/dusk.
