2014-2018 Mazda 3 Skyactiv Discussion
2015 3i Sport hatch AT (1k miles)
I set cruise control to 62mph.
my garmin gps says im going 63mph.
my garmin has matched mph for 3 other cars I've used it in. (all cruise control.)
so I have confidence my garmin is reporting the correct speed and my new 3i is 1mph faster than what cruise...
