Without HUD, the NAV info is displayed on the full color driver display at the lower half of the tachometer/speedometer. All you need is right there on the dash. IMO and others, there isn't benefits to the HUD feature as a result, especially when it's invisible with polarized sunglasses. So, many will advise it doesn't add anything to the NAV and doesn't look cool since it cannot be seen. I'm sure some others who have HUD will say it's awesome nonetheless.
