Garmin StreetPilot c330 Troubleshooting
The StreetPilot is a touch screen GPS device that was released in early 2005.
Before replacing the battery or power supply, follow the steps below
Check to see if your StreetPilot is firmly plugged in. If it is, you may have a problem with the power cable. Test multiple sockets to verify that it is not a faulty power source, but a problem with the StreetPilot itself.
Try resetting the StreetPilot. Plug it in. Remove the gray frame on the front of the screen by taking your fingernail and prying at the slot under the logo "GARMIN". Underneath the plastic frame on the right hand side is a "RESET" button. While it is still plugged in, press the "RESET" button.
Before replacing the battery, follow the steps below
First, plug in the StreetPilot and turn it on to verify that it is a power issue, rather than a problem with the internal working or display. Next, charge the Garmin for an hour and attempt to run it off of battery power. If your StreetPilot dies soon after being unplugged, you probably have a battery issue.
Before replacing the speakers, follow the steps below
There is a volume knob on the top right side of the device; turning the wheel clockwise increases the volume. Verify that your device has volume on and is not muted.
If the device is low on charge, the volume may not function properly. Try charging the device or plugging it in to make sure that it is not a power issue.
Nothing above describes the issue you are having, or the issue was not resolved after trying all possible solutions.
