I have a new Dezl 770 HD. Although I am a Garmin fan this thing has some serious mapping problems:
- Often it wants me to turn the wrong way out of a rest Area or truck stop, drive anywhere from 1 to 14 miles, and then make an U-turn. It even tried to take me on a ferry. When looking on the unit for a truck stop or rest area it shows them both ahead and behind me. Who in their right mind would go back 300 miles to a rest area?
- When travelling through large cities the map is full of icons for food and ATM's. This is a trucker GPS and almost none of those icons are truck accessible.
- While driving from Reno to Sacramento it missed all the 5 & 7% grades. NO WARNING. I do not trust the city routings!
