So what happens when you connect it to the PC?
Make sure no sd cards are installed while you do this.
download and install web updater, run it it gets to a screen where it looks for the gps, plug the usb cable into the GPS (no USB hubs please!!!) Make sure it detects the GPS before you continue. Select the updates you need (don't install all the languages !!) after this is done the program will report the downloads are on the garmin, unplug the unit and it will reboot and whilst rebooting it will install the updates....so don't touch it until it reboots again and displays the regular screen....and make sure the batery is fully charged before you do this...!

SOURCE: my Garmin Nuvi was working
Here is an email received directly from Garmin: I have tried this myself on several units and it worked. I can't gurantee it will work for all cases. In some cases the antenna may be defective. Also, click on the "wrench" symbol, then the "gear" symbol and then "about". Look at the number after the text "GPS S/W:" It should be a number like 2.9 or 3. If its 0.0, then the antenna is not communicating with the main board.
"Thank you for contacting Garmin International, I am happy
to help you with this.
Sometimes the almanac data that your nüvi stores for satellite acquisition becomes corrupted. This causes acquisition to become slow. To correct this we need to perform a master reset. This procedure will erase all user data.
With your nüvi powered off, press and hold the lower left corner of the screen. Next, turn the power on. Continue to hold the screen until it asks if you really want to enter maintenance mode. Next, choose clear user data. The screen will flicker a bit and then start up like it did when it was first turned on. Follow the directions to set time and location. You will have to reacquire satellites by turning on your nüvi with the antenna up outside in full view of the sky. This one time
acquisition may take up to 30 minutes. "

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…….

Let's assume the unit is in good conditions. When you travel for more than 500 Kms the unit need more time to acquire the satellites, so the solution is to keep the unit on in a uncovered area for about 15 minutes.
