Thread: Garmin 765T will not connect to PC with USB cable.

A friend of mine gave me his Garmin 765T as he bought a new GPS. I wanted to run the webupdater and update the maps etc as the maps are the 2010 maps. I am using the supplied garmin USB cable which by the way works with my Nuvi 200 so I know the cable is not the issue nor is my USB port. Anyhow when I plug this GPS into the PC I get the screen with the PC on it however nothing happens in Windows. The device is not seen, it does not show up in disk management, it acts like it is not plugged in at all. It shows the PC icon for about 20-30 seconds then it just turns on like it is skipping past the USB mode. I have the latest webupdater installed and I even installed the latest UBS garmin drivers. It simply does not act like it is connected. I installed a SD card and tried again, still nothing (thought the SD card would show up as a hard drive). The GPS does read the SD card as I can see the photos on it in the picture viewer. I am confused as to what the trouble could be. If I go into the diagnostic mode and the first screen where is says "USB ID", that changes from no cable detected to USB Type B when plugged into the PC. Any suggestions? Not sure what else to try. It seems to work fine just want to update the maps and firmware if there is any update available.

Also when in PC mode a bar appears above the PC icon/logo, and a green status bar barely starts to move then the whole status bar disappears.

Thanks!
