My 800 has stopped communicating with the computer. It charges but doesn't show in the finder. Have tried different leads and computer so definitely the device. Have done a hard reset and a boot block, but no joy. Any other ideas before I pay Garmin £75 for a replacement?
I had a similar problem, replacing my cheap ebay micro-SD card with a Kingston one seemed to resolve it. Do you have an SD card installed ? If so, try connecting it to the computer with the card removed.
