Does the Axium have an RS232 port so it can connect to a Garmin or
flight recorder?

It has a "serial port" but not an "RS232 port". You can hook it up
directly to a few GPS units that have TTL or CMOS level serial ports,
but it needs an external RS232 level conversion circuit to interface
with a Garmin GPS, flight recorder, or flight computer...
