Question about Garmin nuvi 780 GPS

1 Answer

Attempted to replace the Map previous saved on my new GPS nuvi 780. I Downloaded the Map to my GPS connected to my computer. Once downloaded, I selected the Icon to unzip the webupdaterforwindows. Problem 1: My nuvi 780 now only displays large freeways and no roads. Problem 2: error; "No Data Available" when I try to select Address. Problem 3: Points of Interest: The only icon available for displayed is Spell name. And I get the same error "No Data Available" once I Select that Icon. Problem 4: The View map only displays major freeways, no adjacent small streets or the closet address or the location will display on the GPS. All of this worked prior to the download. Here is what I've done so far; a. reset the Garmin. b. Re-down loaded the map. c. Tried to turn on your map, I pressed the wrench/tools button, the setting icon, and then the map icon. I looked for the map with a checked box as suggested, but it was not on the option for display to turn the map back on.

Make sure you have the file gmapprom.img on your Nuvi. It sounds like you just have the base map file.

How can i reinstall my garmin on another computer


There is no installation of a Nuvi GPS on a computer that I am aware of.
If you are looking for a way to view the map from the Nuvi on different computers, there is a program called BaseCamp that can be downloaded free from Garmin.
With BaseCamp and the Nuvi connected to the computer via a USB cable, the map and data can be viewed and managed.

Hi, I have a Nuvi 255 (205 series) gps, three years old. Last week the screen went blank, came back grey with 'crosshairs' and a black dot in the middle indicating 'press here'. I did so and the dot moved...

Graham - what your describing sounds like you somehow managed to erase the street level maps and POIs in your Nuvi.

If you connect the GPS to the computer with your USB cable, you should at the contents of the Nuvi directories and find a file called GMAPPROM.IMG or GMAPSUPP.IMG. These are the street level map files. Generally, these are found in the root directory of the Nuvi - or if yours has / and you use a memory card slot for maps - find it in the /GARMIN directory. GMAPPROM.IMG is the name of the first map set and GMAPSUPP.IMG is the name of the supplementary or second map set (if you purchased & installed one). You will likely have only one of these files - and may be named either. The size of this file depends on the area and age of the map. Current maps of the entire US run over 1 GB in size. If you do not have any maps named GMAPPROM or GMAPSUPP, you will not see any street level maps.

Something happened to delete the maps. Garmin will probably NOT provide free replacement maps for you, unless under warranty. If the devices is trashing maps and other files, you probably want to replace the unit under warranty or not. Garmin will, upon return of your old Nuvi - replace it with a factory refurbished unit with the latest maps installed, for $79. You can take advantage of this service by following this link to Garmin Service.

I hope this helps and good luck! Please rate my reply. Thank you.

What happens if i download a lifetime membership and then my computer dies?

Once you've signed up and paid for a lifetime membership it's recorded on the garmin website. When you get access to another computer go to and click on myGarmin. Log in using your username and password. When you click on myMaps you'll see the latest map you downloaded. Click on "Details" just under the map name and there should be a button which says "Download Again". Click on that and you get to download the map to your new computer.

No data available and no maps downloaded

it may just be that the maps are deselected. to correct this go into the tools/settings/map and then at the bottom of the screen in the middle you will see map info tap that and then at the next screen it will show you the maps which are installed if there are any without ticks just tap the box. tap ok and try again if. if there are no map choices then you will need to reinstall the maps on your unit

My nuvi 780 only displays large freeways and no

Have you checked to make sure that the map is checked "ON"?

Please see this link:

If the map is not checked "ON", you will only be getting the Base Map information (major highways - no street detail) and you wont be able to search for places of Interest (POI's).

I have got a garmin nuvi 300 and want update the maps can anyone help please

Go to and download the map install application. Follow all the onscreen instructions and connect the GPS to your computer when told to do so. You will now be able to purchase the new maps. If you have never updated your maps before Garmin usually lets you have a free map upgrade for the first time. You will also need to register your GPS with Garmin to get the free upgrade.

Thanks for using Fixya. Hope this works. Let me know if you have any problems.

Cannot put in states

Is the correct software installed? Have you attempted any installations on the device and have you downloaded any 'add-ons' such as new voices, etc.
Is it new or bought used?
