My Garmin street pilot 3i has stopped receiving satellite reception. It started about a week ago. Since then I've been on the Garmin site and checked for updates, changed the batteries and done a full system reset. None of these things have worked. The unit is just under two years old - any ideas?

Question: Why won't my StreetPilot i-series device acquire satellites?
Same happened to me - try --> Answer: If your StreetPilot i-series unit is having a hard time acquiring satellites we would recommend ensuring that it currently has the most recent version of unit software and then performing a master reset. In order to update your unit to the current version of software you will need to use the Garmin WebUpdater. Here is a link to the page on our website that has the WebUpdater program and instructions on how to use it:

Once your unit has the most up-to-date software, you may need to perform a master reset. To do this follow the steps below:

1. Start with the device turned off.
2. Press and hold the arrow button, wheel, and power button simultaneously.
3. Continue holding these buttons until you see the message, “Do you really want to erase all user data?”
4. Once this message appears, release all three buttons.
5. Select ‘Yes’
