The Garmin GPSMAP 76CSx adds a whole new dimension to the mariner-friendly 76-series navigators.  GPSMAP 76CSx  is a high-sensitivity GPS receiver, barometric altimeter and electronic compass, microSD card slot, color TFT screen and turn-by-turn routing features that have made the Garmin GPSMAP 76csx Handheld and its counterpart, the GPSMAP 76Cx, a mainstay among serious outdoor enthusiasts.

If you buy new Garmin GPSMAP 76CSx, it included blank card stores up to 128 megabytes (MB) of optional maps or other data. The card slot is located inside the waterproof battery compartment, so you don’t have to worry about getting it wet. When navigating on the road, the 76CSx provides turn-by-turn directions to your destination. It also accepts optional preloaded microSD cards with MapSource data for your off-road or marine excursions.


How to install City Navigator NT 2009 to your Garmin GPSMAP 76CSx ? and  What’s the difference between City Navigator and City Navigator NT 2009 ?

For identical years, the map data in the two products is the same. City Navigator NT 2009 uses a more effective form of compression which allows more maps to be stored in a smaller space, but it does require newer units; all the units covered by this FAQ support NT, but double check with Garmin before purchasing.  If you’re purchasing new Garmin GPSMAP 76CSx, don’t have to worry about compatibility/shared unlock codes with an older GPS, there is no reason to NOT get the NT product.

How much space on the SD card to the maps take?  As perspective, the entire US almost exactly fills a much better 2 GB  with City Navigator NT 2009. But before installed please check this System Requirements:


  • Includes USB device drivers. Internet access is required for the unlock process. Cable and GPS not included.
  • PC: Windows 2000 or newer, 512 MB minimum RAM, at least 1024 x 768 display, 24-bit color monitor, 2 GB free disk space, USB port, USB cable, DVD drive
  • MAC: Any Intel-based Mac or PowerPC G3 or later Mac, 512 MB RAM, OS X 10.4 or later, 2 GB free disk space, DVD drive, USB port, USB cable, 1024 x 768 display.

Then  the “Unlock Wizard” to guide you through the unlock process. But you cannot use City Navigator NT 2009 to update the maps on your preloaded Garmin device. To order updated map data for your preloaded Garmin device, visit Garmin’s Map Updates page.
