Even before Garmin announced the GPSMAP 78 last week there were rumors circulating about a possible GPSMAP 62, a replacement for the venerable GPSMAP 60csx.  The announcement of the GPSMAP 78 combined with some items I’ve tracked down online point to the fact that the GPSMAP 62 is probably the real deal.  New product pages on the REI site for the Garmin GPSMAP 62, 62S and 62ST are the biggest confirmation.  Although these pages are essentially empty the page source contains the product names, typical for unannounced products. Other twitter references to the 62 and this Hungarian blog post which references a Garmin rep discussing the new unit on Facebook further support the rumor.  I’m speculating, as others are, that the GPSMAP 62 will be a non-floating version of the GPSMAP 78, based on the same electronics, screen and software with a slightly smaller housing.

Yesterday the FCC site published test data which reveals additional information about the GPSMAP 78sc.   The 78 will have the following external ports:

  • USB mini-B port
  • MCX external antenna port
  • 4-pin “Garmin” port

The pictures of the back of the unit and battery compartment look like the Oregon and Dakota which have the micro SD card mounted under the dual AA battery supply.  The battery cover looks more like the Dakota as do the rubber plugs around the connectors which keep out water and dirt.

Unfortunately the part numbers and insignias on the electronic components were blacked out but based on the shapes, sizes and locations of the devices it seems that the GPSMAP 78 is probably based on the STM Cartesio GPS chipset (large square device, slightly left of center) and other electronics found in the Oregon x50.  The big white device on the right appears to be a passive patch antenna.

Combined with the data in Garmin’s announcement this leads me to speculate that the GPSMAP 62/78 are based on the following:

  • Oregon x50/Dakota GPS (STM Cartesio) and electronics (3-axis compass, sensors)
  • Oregon x50/Dakota OS and software with some design changes to work with physical keys instead of a touchscreen
  • Patch antenna on the 78 (possible quad-helix on the 62?)
  • GPSMAP60/76 screen (dimensions and resolution are the same) with enhanced color depth (256 vs 65k)
  • New ruggedized, floating industrial design (78)

As we get more information on either units we’ll post it here or you can follow us on twitter.  Let us know what you are hearing!
