PROBLEM UPDATING MAPS

Purchased a Garmin 255w, registered device on garmin website,proceeded to download update for map, download failed at 73%. Tried again, same thing. Spent 2 hrs with garmin tech support only to have them tell me to return it and exchange for a new one. Brought new on home, same experience with download exactly at 73%. Spent another 2 hrs on website and phone. Message on gps unit reads "No Detailed Maps Found That Support Routing". Followed instructions on website FAQ covering message on unit but when it says "touch map info" this button is grayed out and is unusable. Can you help me before I return it once again and exchange it for a different manufacturer.

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.

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!

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.

Update file on garmin corrupted


Same happened to my Garmin Nuvi 760, power failed during upload. Files corrupted. Garmin could not locate it with Sat. Told me to trash it and they would give me $70 towards purchase of a new one, which would not fit in my cars receiver. My solution was to purchase a used one that had a good Garmin File folder. I copied the folder to my pc. It was important to remove the device file from the copied folder. I then formatted my corrupted 760. Then copied the folder from my pc into the formatted 760. Next step was to use Garmin Express to replace the missing device file, do the updates, and reinstall the maps. Product code to unlock maps was inside the rear plastic housing to unlock the maps. Whole process took about 4 hours and it works like new now.

How do i download a maps update on my nuvi 300


Garmin offers two kinds of updates on its website: software updates are free. Map updates are not. You'll need a USB cable to connect the Garmin to your computer. Then go to http://www.garmin.com
On the web site, first register your product. Then look for "Support" and follow their instructions for updating your software. After you've done that, look for "Maps" on the menu at the top of the screen. You can either purchase updates one at a time, or buy a lifetime (of your device) subscription. By the way, maps are huge files, so plan on it taking several hours to update your maps even with a fast internet connection

We have a garmin nuvi 255w. We need to know what is the latest map update. Our gps has "CN North America, NT 2010.30" version on it. Is ther something newer than this.


Maps for most GPS devices are updated several times a year. Your map is from 2010 and should be updated. You can go to the garmin site and pay to download and install upgraded maps or do a google search for map upgrades and you'll find some services offering lifetime upgrades for a few dollars more than the Garmin one time upgrade. I did this and have had no problems updating the maps on my Garmin Nuvi 250.

I was just given the Garmin 255W as a Christmas gift.Can you purchase the lifetime maps or do you have to pay for each update after the 60 day free update is over.


There are no lifetime maps for your Garmin nuvi. Garmin updates their maps over time, so there are no lifetime maps available for the device. There are free maps and you can buy maps from Garmins website.
