On my Wife's car, the 2001 Pontiac Bonneville SSEI, the HUD seems to be a lot dimmer than mine on my 2004 Pontiac GTP ? I see the listing on new HUD's but not sure if it is the HUD or what, but it is a lot harder to see as far as the brightness then mine is.Is there a way to increase the brightness other than the outside setting with the knob?
