Hi,
Can anyone advise me, I download PowerMap Z9 for Thailand and when I unzip file I put all folder and file to MicroSD card and insert to China GPS machine, but when I run program it come up with PowerMap logo with welcome voice for a few second and then it disappear. I don't know why this happened. And I confirm that under PowerMap Z9\Maps there are R21... reside there already. I though I did all step correctly. I run program via MobileNavigator.exe but when I run program via C1B4800.exe, C2B4800.exe, C7B4800.exe and C3B9600.exe it didn't work at all. My China GPS is support resolution 480 x 272. I'm waiting for your guys answer. Thanks!
