I love my new Garmin 1390T but I can't seem to get my computer using Windows 7 to run the auto run .exe file when I plug it in. It's seeing the drive that it is on but when I click on the file to run it there is only info printed on notepad. I was able to register the unit, it saw it when it was connected to my computer. But when I went to download and update the maps I couldn't complete the process. It told me to unplug the unit after the download and then turn it off. Then to reconnect to the computer and turn it back on. I keep getting a pop up asking what I want to do and when I click on open file and run the .exe it just pops up with the printed notebook page with writing on it... Can anyone help?
