So I think I may of fried my USB connection on my 76csx. I direct connected a USB plug to my motorcycle battery and plugged it in. Now its not completely fried, when I plug in a power cord it will get power. But when I try to connect it to the computer to connect to mapsource, it isn't located by the computer. I reloaded the USB drivers from garmin and reloaded Mapsource, but still nothing. I even caenged computers, still nothing. Tried different USB cables, nothing. When I switch it to Mass Storage device, the computer won't recognize it. In the settings the USB connection states "not connected"...I made sure it says "Garmin" under the connection.... Garmin says its $110 for out of warranty repair.....everything still works on it, but I can't add anything...like track, maps or way points. Ideas??
