Comments on: N95 A-GPS the mystery solved http://www.edparsons.com/2007/07/n95-a-gps-the-mystery-solved/ The blog of Ed Parsons, Geographer.

Ihe GPS works much faster now. However II have discovered a few problems: 1. When I use the "Show route" option I get the turn by turn directions but the "Start tracking" is missing. I had been using this feature extensively with V11 and miss it. Can that option be put back. I would pay extra to be able to download it. 2. The "Show on map" option gives me the directions on the map, but not my current position. I have to use the scroll key at each turn to display the next leg of the journey. This may be OK when walking, but is downright dangerous while driving. 3. The distance, when the distance is less than one mile, are in yards. I would prefer 10ths of a mils as that is what my odometer reads and I have to do the conversion in my head while driving. Quick, how far is 485 yards in tenths of miles? (I set the System of measurements option to "Imperial.") 4. Whe i go the the "Find place" option, then select "Nearby" it does not display the landmarks English, but what appears to me as German. I don't know how to change this to English (US). 5. There seems to be a change to the Maps of Mexico, specifically Baja California. Previously the airports of Baja, including dire landing strips were indicated on the maps. Now these are gone completely -- even major international airports like Tijuana and Los Cabos. Moreover, the roads are no longer trackable with the GPS and many of the minor roads that were visible before are gone. I would like the old Baja maps back.

I still find some things confusing with this AA-GPS. I thought with A-GPS the N95 would still need to locate itself via something like cell-based location, inorder to work out which of the sateliites it's closest to from the assistence data (from the Nokia server). For example if you fired it up for the first time in a city, even with knowledge of satellite ephemeris data, it'd still need to have a rough idea where it was to choose the right/closest signals. right?

You will need to use a network based application (i.e. not on your phone) for this to work. This is a business rather than technical issue as the operators charge per location fix.. This will give responsible accuracy in urban areas, say within a few hundred metres but will not work as well in rural areas. Peter,

Maybe only for Telstra subscribers (I'm using one of their 3G cards), but an unexpected bonus. I have yet try it in regional areas where other forms of coverage are not available but where Next-G is meant to be present.

I had updated my firmware (what a drama that was!) but hadn't realised the availability of assisted GPS. What I haven't been able to achieve since the very first time I used the phone's positioning feature (ie before I downloaded maps) is positioning using cell locations when satellite signals are unavailable, such as indoors. Any suggestions? Thank you Ed. I had updated my firmware (what a drama that was!) but hadn’t realised the availability of assisted GPS.

Then you need to replace the vodafone firmware with a generic version instructions here http://clear-nokia.blogspot.com/2007/05/nokia-n95-debranding-guide.html You can then use the Nokia software update.. Another benefit of this is you will get VOIP on your N95 which vodafone removed. Rob,

I checked this yesterday using the Nokia software updater, but it picks up my vodafone product code and tells me i have the latest available version of firmware? Version 11...26. I called 191 but they didn't seem to have a clue. Any ideas. Rob Ed,
