Nextar Q4

Hi,
I have nextar q4 with its 2gb sd card having north america maps.
Are there maps for Africa to be used on this device and how to add
Thanks

Hope some one have solution

finally I figured it out. Just connect the gps to computer using active sync, from there browse the resident flash and look for autorun.inf
Copy that file to your computer desktop, edit it and just put: \explorer.exe\ then copy back to same place on the gps (remember to backup this file in case you need to undo the changes already done).
Disconnect from computer, reset and here we go...you are now on win ce desktop with mydevice icon there.
Now you can install any gps software like garmin mobile xt or other software like miopocket, media player, winzip.......
Would be glad to answer questions (hope I have answers to then) :)
