The 7720 is a great unit with a super cool look and feel. The 7720 doesn't seem to take any longer in calculating a trip that it's predecessor the 7710. Any GPS will take a long time to calc a route if the unit doesn't have a good lock on the sky...
So far the 7720 has been well received. Our customers are very happy with the new unit even when compared to the 7710...
Planning to
buy an RVND 7720 with Lifetime Maps? Be careful where you purchase. When shopping super discount sites, the manufacturer will often not honor the warranty.
