Question about GPS
Here is an email received directly from Garmin: I have tried this myself on several units and it worked. I can't gurantee it will work for all cases. In some cases the antenna may be defective. Also, click on the "wrench" symbol, then the "gear" symbol and then "about". Look at the number after the text "GPS S/W:" It should be a number like 2.9 or 3. If its 0.0, then the antenna is not communicating with the main board.
"Thank you for contacting Garmin International, I am happy
to help you with this.
Sometimes the almanac data that your nüvi stores for satellite acquisition becomes corrupted. This causes acquisition to become slow. To correct this we need to perform a master reset. This procedure will erase all user data.
With your nüvi powered off, press and hold the lower left corner of the screen. Next, turn the power on. Continue to hold the screen until it asks if you really want to enter maintenance mode. Next, choose clear user data. The screen will flicker a bit and then start up like it did when it was first turned on. Follow the directions to set time and location. You will have to reacquire satellites by turning on your nüvi with the antenna up outside in full view of the sky. This one time
acquisition may take up to 30 minutes. "
