I have had two continuous issues with my 2014 Mazda 3; the navigation system shuts down and then begin a cycle of continuously shutting down a rebooting and the heads up display at times does not pop up when I start the vehicle.the only way to stop this is to pull over, shut off the car and then start it back up again (this generally fixes both the navigation and hud issue, although these issues do not seem to be related as the have not occurred at the same time before.) this certainly seems like a software issue as rebooting does fix the problem. This happened multiple times and mostly occurs at the end of long trips, when I need it most. In some instances this has led me to take wrong turns in heavy traffic or forced me to pull over in heavy traffic in order to figure out where I am going. Mazda needs to deal with these issues as they can pose a safety hazard to those following the navigation directions. As always do not depend solely on a navigation system, especially the one in the 2014 Mazda3. It will enter into a cycle of continually shutting down and rebooting when you need it most. I have brought my vehicle to a dealer to update the software to the latest version a few months ago, it did not fix the problem. I went to a dealer for a recent oil change I mentioned the problem and they did not even seem to know what the latest software version was or why I would want it updated. I hope that most dealers would update the software for a car under warranty when they complete an oil change, or at the very least know and make the customer aware a newer version of the software is out so an update can be scheduled. I plan to complete this update, but no one at the Mazda service center I went to was able to tell me what the update changed/fixed. I am highly disappointed in the vehicle's navigation and hud. Caveat emptor when buying a year one model.
