Trying to download an update for the NUVI 255W, that I purchased a number of years ago. Not having any luck getting through Step1 of 2. " preparing device for map update." Anybody have any suggestions, factory emails haven't been very helpful. Garmin Express seems to have downloaded to my PC ok. Sorry I spent $$ on the upgrade. Thanks for any suggestions.

I have found from experience that it will sometimes take a very lonnnnnnnnnnnnnng time for it to prepare device for upgrade. I have even set it up to go and then go about my business for a few hours to let it work. How long do you wait before cancelling the process?

My suggestion would be to go to the Garmin website and ask the question. Has the unit been registered? I'm wondering if it is too old maybe the Garmin Express will not work.

Call Garmin. I've needed assistance a couple of times and when I called got a very helpful person.Just FYI on your 255W. If it's been a while since you updated it the internal memory won't hold the updates. It requires loading the updates on a removable disc. Before loading to the disc the disc has to be formatted. Then do the updates and insert the disc into the 255. I've got a 260W on my bike and that's the process I go thru every 4 mo updates. The updating actually goes quicker loading to memory card than it did when it went directly to the GPS.

Delete and reload the garmin downloader. Had problems with one of mine and that fixed the issue.

agree with deleting garmin downloader and reloading it. also it can take up to 5-6 hours to update depending upon the speed of your internet connection.
