My 2015 Chevy came with one I would not buy another truck without one. No more jumping in and out of the truck to see how close you are. Even better at the Hotels when you can’t stay hooked up to your boat.
With the Gen3 out I would think anybody that still has Gen2 will be dropping the prices soon, make sure to get the update that just came out in January. Its a free down load from their website.
