So pratically you are confirming that a Nokia Lumia 820-920 are both working as full GPS, so if you set the phone as roaming disabled it'll get your position and the drive will actually work. Because even if the AGPS is only used to kick it off, for a 1KB exchanged you might pay your provider 3 pounds so it's not the case. Off course the maps I need are already in the phone memory, I do it at home usingthe wi-fi. The positioning accuracy never gave me any problems with drive and walk mode with my old Nokia C6-01. with the application running totally offline with no exchange of data, even if I knew it was off many meters. It used to take a bit longer to get the sats the first time I used it, but after that it was fine. In the woods you always have accuracy problems even with a Garmin for hiking and the position can be off many meters, and not just in the woods, but in the open areas like fileds, in the wind or if it's cloudy, and anyway with a C6-01 I used to track my walks in the woods and it was working pretty well I have to say, it was an impressive little phone, but it was a Symbian Belle.
The problem here is to know before buying the new phone IF the Map and Drive in WP8 are working as a full GPS or ONLY as assited GPS, meaning that if you set the phone with roaming off, it won't work. So the question is, are the Nokia Lumia 820-920 full GPS or strictly AGPS. The problem about the applications giving online information connected to your position or the download of the maps are not the issue

a-gps uses a fractional amount of data to help fix a position with the actual gps. during initial positioning it connects to a cell tower (or more than one tower) and sends the identification info for that tower to central servers (supl servers). these servers send location info back to the phone which tells the gps 'roughly' where the device is on the planet. this speed the gps fix a great deal. either turn off data (or roaming data) in settings or turn drive to offline mode and it will block the app from using data. maps does not have an 'offline' option, so to ensure that does not used data, you have to have data off in general settings.
maps does NOT have an offline option. even if you have downloaded a map for drive (which you can use offline) does not mean it works offline in maps. i am not sure if maps even uses the same map/data.
a great feature would be the option to switch on data just to get an initial fix then switch it straight off... this is what i sometimes do manually when i am roaming to get a fix because it can take 15-20 minutes sometimes to get one on pure gps. Nokia should consider adding this option.
i am talking about lumia 800 and 900 here.
Hi, thanks for your replies
How could I see that the offline Maps are working in "real" offline mode in the specification?
The specification for the Nokia C5, which I currently use, says:
Navigation features and services
If I want to use the C5 in "real" offline mode and the roaming turned on, I have to disable the A-GPS function, which uses the network.
In the Lumia 920 I can't see that the feature GPS is available, it says only A-GPS.
The device specification page for the Lumia 920 gives the following information regarding positioning and navigation;

im from singapore. i have problem with my GPS
1. cannot lock in position (sometimes it works but position way off from actual position) i have done calibration using city lens & compass.
3. Nokia singapore service center loan me N9 and i tested the maps offline and online mode it work PERFECTLY FINE AND EXCELLENT.
4. Can i exchange my new phone seem like the nokia service center guys say they need to operate the 1 month old lumia 920 because they don't believe nokia maps & navigation can work offline. he say Nokia Maps/gps/navigation require data and wifi to work, basically he want me sit tight at home to use the fantastic maps. what a joke!!!
i do not like my new car to get overhaul i believe all of you feel the same. Any one please help, i really frustrated lumia 920 will be my last nokia phone if no solution with the **bleep** and stupid service center guys @ ViVO city
