Do you want to pull your tracking data from this site down to the LEAF's NAV screen? If so, how would you want it displayed? List format? Map format?
Assuming I'm on the right track, what you want to do is more or less possible. That site has an API for which you can get data and re-format it into an RSS feed that could be read by the LEAF. Because it contains GPS coordinates it is possible to use the LEAF's NAV system to allow you to view (or set as a destination) any of the points it retrieves from the APRS server.

You might be able to pull data from the canbus, which might be the only way....
you'll probably need to put together an arduino or something to read the canbus and spit out compatible data for your ARPS device.

I expect a number of useful things could be monitored by analog methods. Some strategic thermocouples and maybe a voltage divided/scaled tap of the main drive battery pack. I am not sure of the capabilities of your Argent Open Tracker+, but suspect they are similar to the Tiny Trak4.
I'd be interested in other methods of connection and conversion for sending telemetry out via APRS from the LEAF.

In the current firmwarw (F1.08), all of the CAN messages (from the Selected CAN bus) appear at 115200 baud (in 11-byte binary format, for compactness) for logging, usually "recorded" by my free CAN-Do program running in a PC. In CAN-Do, a "Dashboard" screen will even show some of the data in real time, while logging.
A small change to the GID-Meter firmware could add an "APRS Data-Stream" mode to send just the desired data values, at a selected baud rate, in the required format.
Give me an example of how you would like to have some "typical" data formatted. For example, how should ... GIDs, PackVolts, PackAmps, and RPM be sent to you?
(going about 94 mph backward )
Send as ASCII characters, 2400 baud, "7,n,1", with no flow control ... or what?
How often should it be sent to your APRS system, ... once a minute, once a second?
