The way the Micro SD / SD cards work is: Once you arrive (outside the US) you install the chip into your Garmin (all of the maps are on the Card and stay on the card they do not load onto your Garmin). Turn on your Garmin: The Garmin may or may not prompt you to choose the country you are in (it will take a few minutes for the Garmin to reboot and access the Garmin Satellite and verify your location. I have never heard of the maps needed to be unlocked? You may have to perform the actions above more than one time to get the chip to load on your garmin (once outside the US)

The garmin maps are no good. Pretty outdated and are not life time. You need to download the latest maps if updates are available.

I am having this problem, as well. I tried to run updates and had it plugged into my computer most of the day yesterday and then last night it just would not turn back on. I have tried the reset on the switch (my 255 does not have a reset button, i ripped of the sticker to be sure) and I just can't get it to turn on. Garmin support has a 30 minute wait time and I can't wait that long at work. Anyone have any other ideas?

Don't know. Suggest you contact Garmin via telephone or use their web site.

There are no maps at all, on it. You must purchase maps I highly suggest hunt my maps over Garmin maps

NO. I tried to install a Garmin SD card with maps of Europe, and the unit says the maps are corrupted. I bought another card (new, factory sealed) and the same thing happened. In both cases, Garmin customer service said that they don't understand why the cards don't work (but if you search their support site, there is a reference to this problem and you are told to contact customer support). Garmin Customer Support said that the only way to make the unit work is to buy and download maps directly from their website. But the Nuvi 66 doesn't have nearly enough internal memory for Europe maps so you are forced to buy a microSD card and copy the maps to it after downloading them. After wasting so much time, I didn't have time to do this before leaving for Europe so I wound up paying 18 euros extra per day for a rental car with GPS for a total cost of $375! Garmin should be ashamed.

Follow the following steps: 1- Install the Garmin App on your PC; 2- Connect your GPS to your PC through the USB Port; 3- Format the Drive; 4- Reinstall the Maps. You may need to insert an SD card in your GPS SD slot, if the map size is too large. That should do the trick. Your device would be updated to its latest version as well as the maps. Good Luck!

Never thought to check Garmin. I did everything listed on this thread but in the end the thing that seemed to work (after all of the above!) was to uninstall leappad connect and reinstall from their website (not the CD)

Petersen:Try e-mailing tech support instead.I e-mailed tech support (techsupp@garmin.com) instead of product support and have been told I'm in the order que, at no charge, for the DVD of the new v. 2008 maps when the DVD is released. I explained my situation and asked if they could help me out, as the v. 2008 is now really the "current" version, and they did. (I received my unit about a week ago from Amazon with the old maps; the new version was already being shipped to some customers at that time.)

https://pioneer.naviextras.com/shop/portal https://pioneer.naviextras.com/shop/portal/downloadsYou need to download a SW (no Mac, just Windows) and then download the updates for free. You can also buy maps from another regions, but very expensive comparing to Garmin.There are limited areas maps, I can't find for example South America, just Brazil.

"Wake-up" the Garmin by pressing and holding Mode and Reset for 3 seconds. If that does not work, reset the unit (should not lose saved data) by pressing Mode and Power simultaneously.

Maps in Garmin format (not protected, for example Lambertus/opensteeetmap.nl) could directly be downloaded to the device or SD card on the device in USB mass storage mode when you see the device and inserted SD-card as disk drives. The same works with GPX tracks.

I believe that for a fee, you can download Europe Maps from Garmin. I'm sure this takes time, as updates take a few hours over hi speed internet.

I think that you should download the driver (Content manager) for the device. Just go to the Magellan webpage. I had a similar problem some time ago but I solved just downloading the driver, and now is working perfectly, even updating maps!
