I know there have been many posts about the heads up display not actuating and the reasons. Here is my story. I have a 2014 Mazda 3 and as of lately the heads up display was only coming up about 50% of the time. It has gotten progressively worse. When it didn't actuate I would shut the engine off and restart the car and the display would come up. Now a couple weeks ago the engine stumbled when I started it and it acted like the battery was going dead. Lucky the car starts on the first crank. As the battery was the original I changed it out for a new battery. Low and behold since I have installed the new battery the heads up display has not once failed to actuate. Now this leaves me to believe the poor activation has something to do with an initial charge of electricity. Any other thoughts out there?
