Hey guys, the HVAC trick worked on my 98... pretty cool, and thanks. So I set my GPS to kph drove down the road and compared... still a difference, but doesn't seem as much. I forgot to note the difference, but will do it again later today. I will then calculate the error and compare (HVAC vs. speedometer). I will assume my GPS is accurate (of course). Chris
