Actually you are not describing a failure of your GPS. it was working perfectly.
You are describing a failure of the Cartographers who wrote the map for the GPS.
The gps has basically one duty. To properly report your geographical location in 4 dimensions (Altitude, Latitude. Longitude and Time) It may also carry "optional information" to your receiver (Weather. Alerts, Traffic) but that is just "Radio" not GPS.
Translating 2 (or even all 3) of the GEO varibles (Lat, Long, Alt) to a spot on a map or represention of a building.. Well that is the job of the map maker. and the map software.. Locating a nearby "Attraction" (Target destination) is yet other optional software... And part of the map package. NOT THE GPS. it just runs the map program.
Your smart phone has another advantage. IF a new store opens. it will knwo about it almost before the ribbon is cut.
