Sorry for laymen question - we've just bought our first car, so have no experience with what to expect from GPS devices. We've bought Garmin 2597 LMT, and it slightly didn't meet our expectations. The reasons are the following:
1. By some reasons, the address of one of the buildings (my work address) is absent in the maps. The building was built in 2007 in the center of Cambridge, MA. Map updates didn't help. Also, my sports club can be found just by address, not by its name.
2. Google maps at my Samsung Galaxy sometime tells what lane to take even on the roads within small town. My Garmin never does that. We didn't go to highway yet - perhaps, lane assistance works there well.

Our concern is if we should return Garmin and purchase another model, perhaps, even another make (TomTom or Magellan). Or these missing addresses are common for all GPS, and lane assistance can't be compared to Google maps?
