I've made multiple long distance trips and heavily relied on the nav. I was especially thankful when I did not have cell reception for certain stretches of the drive. Yes, the screen is on the smaller end compared to some smartphones, but the screen's landscape is well utilized. It can also become inundated with a plethora of additional markings and tags but the systems is quick to make call outs once you need to make a turn, for example. Additionally, the system itself does experience noticeable lag but it has operated effectively for the most part. Regardless, I would purchase the Nav again as it is a convenience factor, for me, and performs as expected.
