$26 a piece, when order from UK store, doubt whether you can get anything cheaper than that, http://internettablettalk.com/forums...t=24453&page=2, thread #17 and get a 3 yr licence of Navicore for Europe, just in case you are intresest in Europe visit.

Edit: got an update, that does not work. Need to order from US store, and it may be $44 or $34.

What is wrong with my setup, please?

You could try uninstalling maemo-mapper, doing a hard restart (shutdown+drop battery), and reinstalling maemo-mapper.
I uninstalled it doing the hard reset. The behavior is the same. I noted that after some time searching a gps receiver without success, MM says
Error connecting to GPSD server. Retry?
but I have Settings => GPS set to File Path /dev/pgps
How to fix this if it is the source of problems?
Again, I have no trouble if Wayfinder is launched firstly.
What setting could be wrong or what file is candidate to be corrupted?

Control Panel Location settings are obviously correct as Wayfinder works (and uses them), in Maemo Mapper set the connection type to Bluetooth and no MAC number, this will force MM to use the Control Panel settings.

Bingo! It works now without the error. Many thanks Lardman.

I'd been haveing reasonable performance with the internal GPS until recently when my nvd_data file got corrupted. None of the tricks I wrote about were working -- back to the drawing boards. I did additional experimentation and found some helpful tools which ultimately put me strait. I verified that there clearly is something different about Maps and Maemo Mapper when getting a 1st fix. Strange though, even though Maps got a fix with the corrupted cache, the cache remained corrupted after Maps terminated. I did a rewrite on my GPS lock troubleshooting section.

http://fragostech.com/MaemoMapper/#lockfailure

It suggests installing some addition packages and goes through the process I took in detail to return to a working GPS with Maemo Mapper and a valid nvd_data cache. I'm now back to the 2 to 3 minute time to 1st fix. I'm left with the question -- will nvd_data become corrupted again and did I play a role in that corruption. For the mean time I plan not to terminate Maemo Mapper until after it has a GPS fix. Time will tell.

@Fragos: I hate to sound like GA, you mind to forward what you did to the bugzilla bug? I think they would very much appreciate to find something MAY work. For me? I really wish Nokia should start to get serious with this.

For reference, I've got a Belkin F8T051 which is stellar -- in the Manhattan canyons, or stuck under a Brooklyn EL -- it locks in just seconds. I got it off e-bay a few years ago; I'd be surprised if I paid as much as $45 for it.

Took me about 3 months to get my first lock on the N810 -- finally, after deleting nvd_data, facing south, under clear sky, and killing a chicken, I got a lock in a few minutes. Just leaning back on my terrace, though is enough to send it hunting again. I used MM to track a bus ride down 14th street - it was comical, looked like a drunken sailor going home. It had me wandering from 15th to 12th streets. Even a walk through Chinatown looks like I've been crossing the street multiple times (when it doesn't have me walking through buildings).

I think the A-GPS is just a placebo to keep us distracted until the warranties run out. It's never done any discernable good for me. I think the GPS chip is just a POC. I'm glad I held on to my Belkin GPS.

The N810 is laughable as a real navigating device -- my wife usually has the foresight to print out a mapquest page so we're not totally hosed.

With a 3rd party GPS chip connected via BlueTooth, and either Maemo Mapper + 3G or Navicore I find it pretty acceptible. (Its also neat to use it for OBD statistics as well.)

I did what asked. Hopefully it will give the developers additional insight into the problems.
