There are currently no AU comments for this post.So, how is the phone supposed to read the automotive gps device unit receiver data?

A-GPS can recieve satellite GPS data like any other GPS device.

It’s supplemented by triangulation from cellphone towers, and in the case of the iPhone, WiFi hotspots with known GPS coordinates.Cell phones have a feature that allows a phone to triangulate its rough location.

They get their locations from cell phone towers…kinda like a gps wannabe…GPS different from plain old GPS in the fact that it gets the majority of it’s positioning from things like cell towers and not actual satellites so you wouldn’t actually need a good satellite antenna.: It was a bit like reading alphabet soup at first glance.That’s incorrect.

Emergency services may use that feature to find your location.A-GPS is basically vanilla GPS, but it also leverages that nifty GSM feature to give your rough location quickly while you wait for a GPS lock (or in lieu of GPS if you can’t get a lock), so it’s a bit more useful a bit earlier.guess i will have to wait till i get my g1 not to buy thisWith the number of times AGPS has been mentioned on here in regards to the iphone you would think there would be little confusion what AGPS is.
