AFAIK latest Mapking (Mapking 2007) using map with the *.m7a extension. for *.g10 extension was use for the earlier version. So if you download map with the extension *.g10 and wanna use it for Mapking 2007. You just change the extension from *.g10 to *.m7a

I try to help...hehe...

There are 3 things you need...
1. A working GPS hardware in the phone
2. A GPS software like GARMIN, Agis, etc.
3. An assisted software for downloading the latest satellite positioning.

Without no. 3, it would be very difficult to get a fix. Almost all PDAphone which has a GPS has some sort of no.3 software version.
Some call it enhance GPS. You'll need to GPRS or WIFI to download the latest data into it. From then on, if you on Garmin, satellites can be found much faster...and hopefully it fix.

Try to go a different place to get a fix to the satellites, it must be on a clear day without any roof, trees etc....yeah...the fist time is kinda hard...if you manage to get fix...then it will be easy. Do not move, stay stationary...if after 20min also no fix...then something is wrong.

Also, try a different software from GarminXT...there are a few out there.

You can also download GPSgate for better port splitting...but this is not necessary.

If still cannot, remove the leather case, rear cover and make sure you are using original battery...most gps hardware are behind the handphone....

Still can't get a signal...try google around for your model. Each model has its own quirks with gps

hope it helps.....i'm also trying to configure an omnia to fix unto  signal...good luck bro...

1. Internal GPS needs to work...
2. Yup...thats the latest, but if it doesn't work....dun give up...try something else...
3. Yup, mine HTC also has QuickGPS...I does help alot...but only download if you are running short of satellites or usually overseas or outstation. If you are usually at the same place, no need to waste GPRS money...unless you are in a free wifi zone:)

Please give some reply after you check it out at XDA developers.
