If your StreetPilot c300 or c500 series device is no longer acquiring satellites please read the article linked below to ensure that this is not being caused by something in your environment:Why won't my unit acquire satellites?
If after reading the above article your unit is still having problems, please ensure that your unit's software is up to date. You can do this by using our WebUpdater® program
If you have tried all of the above suggestions and your unit is still not acquiring satellites, you can perform a master reset by doing the following:
Note: A master reset will erase all waypoints or favorites and will restore your unit to the default factory settings.
- Start with the unit powered OFF and unplugged from power.
- Touch and hold the bottom right corner of the touchscreen.
- Power the unit ON and continue pressing the screen until a new message displays, "Do You Really Want To Erase All User Data?".
- Touch Yes and go through the set up again.
Take the unit outside and let it set with a clear view of the sky for 3-5 minutes to acquire satellites. If the unit still does not acquire satellites after this, please contact Garmin Product Support.
