Garmin's Fleet Management Interface is used by the Tracker2 and the GTRANS cable.  At least two different connector types are in use by current Garmin models - a USB mini-B type and an 18-pin Hirose ST series connector.  The official FMI specification does not include waypoint creation, but it does work on some models.  However, most models create duplicate waypoints for a moving station, rather that simply moving the existing waypoint.

==== Comment Text ====
Not all Nuvis will display the comment text from APRS packets.
The Nuvi 350 properly displays comments, when viewing stations from the Favorites listing. 

Other Nuvis do not, for example the 680 does not display comment or status text at all. APRS objects show up as favorites, but with none of the comment or status text. 

Information on other Garmin models should be added to this table.

==== Connectors ====

==== Mini-B ====
The USB Mini-B 010-10813-00 cable uses an 8.2k ohm resistor to ground on the ID pin to identify an FMI cable.  The 010-11232-00 cable uses an approximately 12k ohm resistor.  Serial signals are 9600 baud, 0-3.3v, inverted (0v = 1, 3.3v = 0).

Numbering is per Hirose data sheet.  On the wiring side, odd numbered pins are on the top row and even numbered pins on the bottom row.

Please note that this information is preliminary and may be incomplete or inaccurate!  The pinouts above were determined by disassembly of a Garmin 010-10865-00 cable and have not been tested.
