You must call Garmin at 1-800-800-1020 they will walk you through plugging in nuvi to your computer (must have usb cord) and it will upload then go to my computer and choose garmin drive then click garmin folder and either find the folder they say or make new one like I did with the guy on the phone and put in code. The only information needed is the numbers on the bottom of the device.... super fast fix!

I purchased Garmin1490t and it says "Cannot unlock maps" / 'No maps Found" Please help


If your Nüvi keep displaying the maps are locked, you will need to erase a file from the units memory. Connect your GPS system to your computer; go to start then 'My Computer', and double click on your device file (mass storage system), there you will see a folder named 'Garmin'.

In this folder are several different files, look for file named gmapsupp.img. Right hand click on this file and delete as this file is causing the maps to lock.

Other choice, could be one read at No Detailed Maps Found That Support Routing

Hope this helps (remember to rate and comment this answer).

Is my gps only for canada, Or for other countres too ? if so whot to do to get additional countries


You can purchase them at the Garmin website. https://buy.garmin.com/shop/buymaps.do
It will have somewhat of the maps from around the world but to get them more detailed you will need to purchase them. If gotten in the united states it should have a full US map as well as most of canada.

I tried to update my new Garmin Nuvi 255w. It now reads as follows, No detail maps found that support routing. The nuvi cannot be used without them. I have a ABI and to help me even to get home is hard....


There are 2 possible reasons for this. The most likely is that the map is not selected. Go to Tools, Settings, Map and press Map Info. Is the map ticked. If not press it and it will tick. The map should then work.

The other reason is that the map may be locked. The instructions for unlocking the map are at http://www.garmin.com/garmin/cms/site/us/support/searchsupport?search_key=nuvi%20770

Why no detailed maps in my Garmin 255W when


tap the screen and it will move it in for more detail or less - if you have a + sign on the right side of the screen you can also press that.

WHEN I POWER ON MY NUVI 255W IT SAYS NO DETAILED


sounds like the map folder in the gps software got corrupted. you will have to connect your device to your computer, get on the Garmin website, and let the garmin site update your device. Once updated, it will re-install the correct folders and maps to their proper place. the gps should work as before after that.

PROBLEM UPDATING MAPS


Plug your GPS into your PC and do not use the Garmin Express program. It will mount as a drive. Delete the maps and software. Then run Garmin Express and do a complete install of the maps and software.
