Nope. Definitely doing something wrong. When I open the assistant app in Windows it allows me to select a drive that corresponds to the SD card on the phone. I "install" the voices and maps that I want and then disconnect and go to the file browser in the phone. From there I can run the SetupMobileMaps.deb file and the application appears to install. But when I run the application it opens, thinks for a second and then disappears immediately. Any ideas anyone?
