Configuring Mapper 1.4 for the 770 hasn't been sucessssful. First, I upgraded to the latest firmware and was able to install Mapper. Reading thru ITT forum messages have yet found the answers I need. I'm using http://mt.google.com/mt?n=404&v=ap.6&x=%d&y=%d&zoom=%d My cache directory is /media/mmc2/Maps. I get an error message that either I am not connected to the Internet or the format above is not correct. I have verified connection to the Internet. I read somewhere that x, y, and zoom should contain a number. Is that true? I wish to download maps of North American. Can anyone help? thaibill
