supreme_style21 Posted February 5, 2009 Report Share Posted February 5, 2009 The HUD in my 02 GP - occasionally around 23 mph and also around 27 mph, it'll go all goofy for a split second... like it spins through every digit in half a second, then returns to normal. The analog gauge doesn't respond to this, as far as I can tell.. too quick. Doesn't to it at any other speed and it doesn't do it all the time. From what I've noticed, it started doing it around 27 mph, and just the other day, I noticed it jumble up around 23 mph. Is this an issue in the HUD itself? Or where it's getting its signal from?

grandprixnyc Posted February 5, 2009 Report Share Posted February 5, 2009 The HUD gets the same signal as the speedo - the VSS line. If the HUD is acting up and the guages aren't chances are its the HUD unit itself. Probably the chip inside... Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted February 6, 2009 Report Share Posted February 6, 2009 My Regal has always done this (two different HUD units). My speedo goes up as well when this happens. It's something with the VSS. Quote Link to comment Share on other sites More sharing options...
Euro Posted February 6, 2009 Report Share Posted February 6, 2009 My GP does it every so often, probably once a day at most if I had to pick a number. Quote Link to comment Share on other sites More sharing options...
