  1. Well to be completely honest its considerably more involved than just the tire rating; many of these trucks have tires rated well beyond the top speed they are limited at.

  10. We still offer a ship in upgrade for those who only want NAV on their IOS equipped trucks. You'd want to contact us on the site for details however most just go with the wireless carplay/android auto upgrade as it comes with Nav.
  11. Again the only current issue is with 2019's with 360 Cameras which we have some new perspective and direction on now and have resumed work on those. ALL other years/models are 100% OEM perfect.
  12. Have to make sure the time zone setting is enabled.
