Most people want a GPS that's easy to use, has theįeatures they want, and suits their needs. Pros and cons of Garmin's 255W are listed throughout the various A Nuvi 255W was purchased from a localįuture Shop, installed, used, and tested. The file names are not corrupt and they can be renamed, but alas not copied.This is an extensive hands-on review of the Garmin Nuvi 255W GPS. But, I still get the message ‘no detailed map files. Unfortunately the only file that seems to be behaving badly is the gmapprom.img guy.īy the way I did rename the gmaptz.img file and let WebUpdater do its thing – it worked for that file. You mentioned City navigator? That is not on this device and do not recall having ever seen it? One day it worked, and the next, it did not *sigh*.īy the way I had already done most of the suggestions Ran WebUpdate, Called Garmin and had a nice long conversation with a very helpful support guy, but he was unable to help as the files for this model are no longer on their server. The device was not (recently) connected to the PC. After running CHKDSK I was able to repair the gmaptz.img file (got back POI’s) etc. In the past 30 years as a ComSci guy you get to know these things. How do I know the files are corrupt? File Explorer says so. If so, don't just delete the old file-either rename it to something like or move it to a computer hard drive so you'll have it available if you ever need it: This Garmin forum discussion suggests that WebUpdater will restore a gmaptz.img file although you may need to remove the old gmaptz.img file first.

With a corrupt or altered filename, you nuvi likely doesn't have room to reinstall or update City Navigator. If the two corrupt files have corrupt filenames as well, get back to us. Is there a chance you ever had your nuvi connected to a computer and you pulled the USB cable or your computer went to sleep while files were still open or being transferred? It's always safest to use the Safely Remove Hardware function if using a PC.Īnd, of course, if your nuvi has lifetime maps, there will be a new City Navigator (2014.10) coming out very soon and that'd update your currently corrupt gmapprom map files. I don't know that a low battery would corrupt these files. Besides being enormous, the City Navigator map files are not something Garmin permits folks to share. Alternately, we've heard that Garmin has no issue with folks sharing files of this sort, so another 255W user may be able to send you the file. If WebUpdater doesn't offer a replacement time zone map, a call to GarminCustomer Service with your device connected to your online computer may let them replace the missing time zone map.

It's possible that WebUpdater may be able to install a new gmaptz.img file. You should have the option in the myGarmin site to reinstall your current map and that would restore a good City Navigator: The gmaptz is the Time Zone map so automatic time zone changes will not occur. What you're seeing now is your Basemap (assuming that gmapbmap.img is still OK). The gmapprom files are your City Navigator map files so you've lost your routable map, built in POIs, speed limits, etc. If there and not checked, just check it.) OK, I said it in the Subject so I won't say it again.īefore getting into solutions, how do you know the two files are corrupt? Is there any chance that your nuvi has simply unselected City Navigator? (Go to Tools/Settings/Map/MapInfo and see if City Navigator is there and is checked.
