Downloading map to 276C

I tried to download a map from mapsource to my gps unit, but everytime it fails and give the following message: "the gps is unable to program the requested memory region. This could be due to an incompatibility between the application and the gps" after trying again, it still fails and gives this message: "The required memory for storing maps is missing from your gps. If your gps uses a programmable data card, check to make sure it is inserted properly" I'm using a blank 128Mb mapsource data card. My mapsource is version 6.13.2. Any solution is greatly appreciated. Musaraun

Re: Downloading map to 276C

I think your problem, as it was my also, is the memory card. I tried with a friend of mine's data card (memory) and is working fine, I sent my card to garming after I talk to them over the phone for an exchange. I have a 276C with 512Mb data card. I hope this help you to solve it. Javier Martinez Valencia-Venezuela

I have lost my Mapsource Setup cd for my Garmin GPS

  1. Download MapSource software updater from Garmin. The version as of December 4, 2007 is 6.13.6, and the trick also works on Map Source version 6.13.5.
  2. Unpack or extract the content of MapSource_6136.exe
    downloaded using WinRAR.
  3. From the extracted files, run MAIN.msi.
  4. Then, run Setup.exe. Note: The sequence to execute Main.msi and then Setup.exe is important to avoid “Previous MapSource not found!” error.
  5. Garmin MapSource now installed.

Lost maps

You do not give very much information to go on.
Perhaps you have downloaded some data such as routing or some other details from your computer via "MapSource". If so AND you have a mini SD card in the GPS, you have overwritten the SD card with the data from MapSource ...the map data on the SD card is now gone!
But the MapSource Data remains.
If you have copied the original data on the SD card, just copy and paste to re-place it.
If NOT you will need to contact Garmin to get a new SD data card.

What you have to do to prevent this in the future is to temporarily remove the Data Card from the Garmin GPS, then download the MapSource data from your computer. Then the MapSource Data goes to the GPS on-board memory.

Hi I have a Garmin eTrex Venture and have downloaded maps from Mapsource. When I turn on the GPS and go to the map page, no map appears on the screen.

Did you download the maps via your PC into Mapsource and then transfer them to the Venture? You have to unlock the maps on your PC with the code which is specific to your unit.

Garmin zumo 550 map update problem

  1. Make a backup of your Zumo by copying all the file to your computer.
  2. Using your PC and MapSource select all the maps then send them to a SD memory card need 2Gig or bigger card.
  3. Try to rename this file to gmapprom.img and replace the same named file in your zumo. (I haven't tried this personally, so if it fails, just replace this with your backup and all will be as it was.)
  4. If this fails, you can use the SD memory card in your zumo and it will use this map instead, but it will take longer to boot your zumo.

Downloading mapsets

Every time you download it wipes the entire memory card. You have to select all the maps you want stored on the card each time you add a new map. To keep from selecting all the maps everytime you want to download you can save the file in your mapsource software then just add or delete maps from your original map list.

All the mapsets that are installed in your PC should appear in the menu bar on a dropdown list. If you click on it you should see "bluechart" city navigator" etc, if you installed them correctly.

Choose one of the map sets, such as bluechart, from the dropdown list and all the maps from that set should appear on the screen.

As you select individual maps from the map set they will be loaded onto a maplist wich should appear under a tab on the left side of your computer screen.

Then go back to the menu bar and pick your next mapset, such as city navigator. A new map set will appear on the screen but the maps you selected from the previous set will still be on the map list on the left side of the screen.

I hope this helps. Please reply if you have questions about my response.

Error message on screen (read message below)

Did you tried to update your Maps? There are two maps inside your Garmin. Basemap which covers all highways and major roads and mapsource source which cover regular streets. Try reloading mapsource maps.

From the "Where to" menu select the little wrench and then select map and then select Map info. What does it say for Map Info?

If the unit is still under warranty, call Garmin and get a RMA. Return the unit to Garmin.

Map problem

There are two type of maps in the unit. There is the basemap which shows the states and major highway and roads and then there is the actual Mapsource maps which shows the streets. If you go to Mapinfo and it doesn't show anything, then Mapsource maps are missing.

With the 2610 you can use a card reader for the Compact Flash Memory card to load the maps. This is much faster since the card reader is USB 2.0 while the Garmin USB is 1.1 Under device look for the drive letter which correspond to the Campact Flash card.
