They instead rely heavily on supplemental location information derived from cellular tower locations.
Bottom line, if you are serious about navigation use a GPS unit by Garmin or some other reputable company, not a cellular phone. The iPhone and Android phones do a lot of things well, but navigation isn't one of them.

The gps in the phone is a real gps. So I do not understand what you mean. A car gps usually have a better antenna then the one in the phone but that is another thing. And with a phone you can use data from the net to get the initial fix. And I compared Google navigation to a Garmin and did not see any quality differences in the routing.
