Garmin Dezl 780:Things we don’t like

1. Fails to choose the most straightforward route:

Some users claim that they didn’t find it accurate when they use it for routing.  Some professional truckers sometimes fail to choose the easiest route, while some extra miles would be easier traffic-wise.  Rather than that, the others features are excellent, especially for truck drivers.

2. Doesn’t recognize major US roads:

Another downside of this navigation system is that it can’t recognize major US roads. In this regard, using Google map on the phone could be a timely solution.  

3. It isn’t 100% accurate:

We find a verified customer who claimed that he can’t put trust on its’ map. During his driving, the GPS signalling him to turn right and when he turned, he found a sigh turning right isn’t allowed for trucks. So you need to be a bit careful.
