ANYTHING! The Nuvi has a USB interface, but it doesn't, by
default, provide live data out in any format. The normal USB
interface is intended primarily for uploading software patches, updated maps
and user-created points-of-interest lists TO the device. Live GPS position data
DOES NOT normally come out of the device. <br>

Certain Nuvi models, including the 350, have a built-in firmware/hardware
feature called FMI (Fleet Management Interface). When the conductors of
the USB port are pulled up or down with suitable value resistors inside a
special cable, the USB interface "automagically" transforms itself
into a classic serial interface instead. This enables real-time download
of GPS data and upload of waypoint data for plotting objects on the
screen. <br>
<br>
FMI also offers a messaging interface that uses the soft keyboard display
normally used for entering addresses to compose text messages for
transmission. Unfortunately all these goodies are in a proprietary Garmin
protocol, intended for developers of custom commercial AVL/messaging
systems. Some details are here:<br>
<br>
<a href="http://www8.garmin.com/solutions/pnd/"><http://www8.garmin.com/solutions/pnd/></a><br>
<br>
Some of the Garmin units that support this hidden mode are listed here:<br>
<br>
<a
href="http://www8.garmin.com/solutions/pnd/supportedproducts.jsp"><http://www8.garmin.com/solutions/pnd/supportedproducts.jsp></a><br>
<br>
<br>
<br>
>From the standpoint of APRS users, the only two devices that can directly
exploit the Fleet Management Interface are: <br>
<br>
o The Argent Data "G-Trans" cable for the
Kenwood APRS radios. This device has a mini-USB plug on one end (to go
into the Garmin), and a 2.5mm stereo miniplug on the other (to go into the
Kenwoods' dedicated GPS serial port). This cable, with an embedded
microcontroller in a "goiter" in the middle of the cable,
translates Garmin FMI live position data from the Nuvi to serial standard 4800
baud NMEA ASCII for use by the Kenwoods and other NMEA-using
devices. <br>
<br>
The Kenwood APRS radios are capable of translating incoming posits received
from other station into NMEA $GPWPL waypoint strings which can be sent back to
many display GPS devices that accept and plot waypoint data. This data is fed
OUT of the dedicated GPS port on the Kenwood radios, BACK to the GPS on
the other half of the serial cable bringing GPS data TO the radio. <br>
<br>
If this feaure is enabled in the Kenwood radio, the G-Trans cable will convert
$GPWPL waypoints back to Garmin FMI format for display on the Nuvi 350's
maps. Details on this cable for the Kenwood radios here:<br>
<br>
<a
href="https://www.argentdata.com/catalog/product_info.php?cPath=28&products_id=113"><https://www.argentdata.com/catalog/product_info.php?cPath=28&products_id=113></a><br>
<br>
The G-Trans cable is also available with a standard DB9 serial plug on the end
rather than the 2.5mm stereo miniplug used by Kenwoods. (The GPS data OUT
should be usable by ANY device (tracker, laptop, etc) that accepts normal
RS-232 4800 baud NMEA 0183 GPS data. The waypoint data IN would
depend on the capabilities of the attached device.) Details on the
alternate G-Trans cable here:<br>
<br>
<a
href="https://www.argentdata.com/catalog/product_info.php?cPath=28&products_id=114"><https://www.argentdata.com/catalog/product_info.php?cPath=28&products_id=114></a><br>
<br>
<br>
o The Argent Data Tracker 2 (tracker & send/receive
TNC) which can use the Nuvi 350 as a GPS source for the tracker, and the screen
as an APRS mapping display and messaging terminal. [The
program code for dealing with the FMI protocols are built into the T2's
firmware.] The T2 has to be connected to the Garmin with the DB9 version
of the G-Trans cable. <br>
<br>
<br>
<br>
Note that these are open-sourced devices, so the program code for dealing with
FMI is visible and can be used as a starting point for developing similar
capabilities in other software. <o:p></o:p></span></font></p>
