I've got a problem when I using my Nokia N900 in Hong Kong, what the Ovi Maps locate function point at is not what I really am, it is but it got me about more than 100 metres away from where i really am.
Just give you more detail about my device
It is a HW: 2204
OS : Maemo 5 PR 1.3 (UK version)
Here are my question:
1) Is there anybody got the same problem? State where you are, where you got this problem, I'd to find out anybody outside the Asia would have the same problem.

What I want to know:
Is the Hardware version to conduct this fault, or it is just the problem of Ovi Maps.
I tried to reach Nokia Care for help, but they just simply replaced my motherboard and told the problem is caused by the board. However, when I made a test again the problem is still. I don't If I should ask them to fix this again or not.

Out of Ovi Maps
I tried to use CloudGPS, any I got my device located and in fine accuracy. What is the different between the purple spot and the blue spot showed up on my map, the purple spot was pointing at the point what is neary my ovi map got.

I am a late buyer of Nokia N900, it is a product before a year time but nevertheless it is a great product. Hoping to see NITDroid 0.0.9 coming and more to things can do on this little compact device.

You could try modRana and see if it has the same problem?

The (Ovi) map data for China is apparently wrong, see bug 9203 & bug 9950.

doesn't sygic mobile maps 10 have Hongkong maps as part of tele atlas asian maps?

try googling:

'Sygic Mobile Maps 10.16 Maemo With world Collection Of Maps-galedo'

It was a strange problem if it is really the map data problem, I tested it on my former N95-2 doesn't found that problem.
I'd ran the same test on 5800 and E72 too. The result is quite same as my N95 except it take less time to located.

And this "Hong Kong and Macau" not "China Mainland"

try googling:

'Sygic Mobile Maps 10.16 Maemo With world Collection Of Maps-galedo'

you will be able to find sources to download teleatlas' asian maps for sygic mobile maps 10

Alternatively you could go to http://www.sygic.com/ and BUY it....

I don't think you can actualy purchase hong-kong map for maemo.. its only available for the iphone through sygic

but I have seen videos on youtube showing that the teleatlas map file for hong kong does work on sygic for maemo

Thanks for you guy who suggesting alternative way to use GPS function, but what I care about is Ovi Maps and its built-in GPS

If you read the bug report, there it is said also that in N95 the issue is fixed, in N900 it is not, yet. Seem to be some political issue.

Did you try modRana yet? With open source applications it is possible to make the fix, if asked nicely and they have time to implement it.
