If I can't install directly, can I edit/remove some maps I won't use from the IMG? Then rename to gmapsupp.img and add to SD card?
One can update the internal maps on the StreetPilot C330 and C340 by using a Command Prompt instruction to execute the Garmin WebUpdater application program.
Use the Garmin MapInstall application program to generate the custom map one wants to transfer, rename it
GMAPPROM.img, and then use this command line instruction to transfer it to the USB-connected C330/C340:
- Hidden Content
- This board requires you to be registered and logged-in to view hidden content.
Note that for the command shown above, the WebUpdater program is installed in the default location of
C:\GARMIN\WebUpdater, and the map to be transfer is located in the
C:\Garmin folder.
This procedure will replace the main map in the GPS internal memory. The C340 has 2GB of memory, so should send a map smaller than 1.6GB(?) only. The C330 has only 1GB memory, so need to generate a smaller map less than 0.6GB(?) via MapInstall. Use MapInstall to select the areas one will use the most, and put those in the internal memory. Then generate another map file (under 2GB) for any additional areas, and put those on an SD card (named:
GMAPSUPP.img in the
SDcard:\Garmin folder). [https://support.garmin.com/en-US/?faq=UsL6MuMMCM8PpgAhUUCqp7] The C330 cannot hold the entire mapset of CNNANT2020.10 (2.79GB)--too large now--but should be able to fit the lower-49.
