I have seen another person asking about the resolution im looking for (640x480) and i gave it a try myself earlier - it seems to work ok from an overlay point of view (just a test the buttons werent all correct on the keyboard section) but what i did notice is that the application itself seemed to be set for a larger 800x480 screen - im wondering if anyone has any idea of how to tell the garmin mobile pc app that your screen is 640x480 to make it fit better ? It still works ok , but i will be missing the right side of the screen which as you might imagine is handy :s
