Actually, I just solved the problem myself...
I went to Garmin's driver download site (http://www8.garmin.com/support/download_details.jsp?id=591) and got the latest USB driver (2.2.1) for the 60C. (Although, it appears that that driver pertains to all Garmin products, not just the GPSmap series or the 60C.) Installation instructions are pretty much standard for Windows drivers, so it's easy.
That: a) Garmin requires special USB drivers for their product is finicky (most USB-connectable products just connect automatically using Windows' generic USB driver), and b) my unit -- which had always worked just fine, and suddenly stopped connecting out of the blue -- remains a mystery. Nonetheless, a driver upgrade was the final step that I needed. (Although, I also swapped USB cables and upgraded MapSource, too, so maybe it's some combination of those things.)

You need to do an auto locate. This also corrects your time issues (wrong date and/or time will be corrected. To do an auto locate do the following.

I had the same problem? GPSmap76S was hung up trying to AutoLocate. It just couldn’t find itself, and it just stopped working all of a sudden one day, while I was traveling. I spoke with Garmin about the problem, and they advised me of an ongoing problem with WAAS. I was told that I should "Disable" WAAS, because the signal from the WAAS satellites had been changed by the government, and Garmin had not yet put out a software update to address the problem, on the 76 units, anyway. Also said that an update "should" come out, in the future, however, no commitment or promise on that. Evidently, once your unit hits one of the WAAS signals, it scrambles up the receiver in the GPS, because mine sure went crazy. The support guy also said, that if this did not correct the problem, I might also want to try a "Master Reset". So here’s what happened.
I disabled WAAS, but this did not correct the problem. The unit was still lost out there somewhere, trying to AutoLocate, so I ended up doing the “Master Reset”. Please read up on this procedure before trying it, and understand that you “will loose” any settings that you might have made to the GPS, along with all waypoints, routes, tracks, etc., however, my maps actually remained in tact? This procedure will actually set the unit back, just as it was when it originally came from the factory. Once completed, you will then have to allow the unit to initialize it's self again, just as you did when the unit was new. If you have forgotten about doing that, it simply means that you need to set the unit outdoors and leave it “on” for a while (15 – 20 minutes), until it actually AutoLocates it’s self, or locks in on your current position. Once this is done, re-do your setting preferences, back to the way you had them before the Master Reset. At the very least, you’ll have to re-set it to the correct time zone, and tell it about daylight savings time. Note: It’s a very good idea to go thru first, and jot down your page settings and main menu settings, before doing this procedure, or the screens may not look familiar to you, once the unit resets. You think you’ll remember them all, but you won’t. But whatever, once you have done the “Reset” and “Initialization”, you must now hook the GPS up to the computer and reload your waypoints, routes, etc, back to the GPS. You did have them saved on your computer, didn’t you? Hope so… If so, you should now be good to go…………….
My unit now works like a champ, good as new, just not as accurate, due to WAAS being turned off. I still don't know if the WAAS issue, was part of the problem or not, but I do know that the Master Reset got the unit back to working immediately, allowing it to locate itself almost instantly. What a relief…………..it’s a little work, but it takes much less time than it took you to read this post…………..
Hey, when all else fails, call Garmin 1-800-800-1020. They are good guys and willing to help, in fact, I would advise you to call them before you do anything, so you can describe to them, exactly what your unit is doing. I am only relating my situation and what happened to me. Your situation may be different…….
