A:AnswerI can't think of any reason why it wouldn't work. Some vehicles however won't support app features. It is all a matter of what your vehicles system will support. If you aren't getting power, the easiest way to check is to go to a local auto parts store and get a free code check. This will allow you to see if you're getting the correct power through your obd2 dlc port.
A:AnswerIt does display the information on both the device and the windshield. The display on the device is "backwards" because of the way it reflects off of the windshield. the windshield acts like a mirror so the image is reversed.
A:AnswerNo, the GPS is in the event your vehicle is older and doesn't support. It uses GPS signals to determine mph (which is delayed and not always dynamic enough to be of benefit).
A:AnswerThere is no GPS in this unit. I used a Navdy now has built in gps, several viewing modes. If your wanting a HUD with GPS, that’s the way to go.
