For all those new Tesla X owners that have no experience with resetting the display.....Yesterday I downloaded V7.1 and after the download, my voice activation of navigation/music/phone did not function. A Tesla tech walked me thru the procedure for a reset and afterwards, it worked as it should. Just hold down the two thumb wheels on the steering wheel for about 1 minutes allowing the center display to go back then show a grey screen with the Tesla logo...Wait a couple minutes and the reboot is complete....If I would have know it would have saved me a call into the service center...Hope this helps
