When my 05 headlights come on at night, the HUD goes out. I had a 06 Grand Prix GXP with HUD and this never happened. Is there some setting that I need to change? Saw nothing in the owner manual. Have had the car for about two months and have not played with all the options, just been enjoying driving it with the top down!
yes indeed....the brightness can be set and it does dim when lights come on. Not normal for HUD to go off when headlights come on. Try setting the intensity/brightness at night......
