[aprssig] D710 Greenlight Labs GPS and AVMAP?

I don't need input from the AVMAP since the Greenlight is always connected.
I just want the output data (waypoints) to show on the AVMAP.  So is it true
that the Greenlight does have a pass-through sub minim jack?

But both the Greenlight and the AVmap have active RS-232 OUTPUTs that would
trying to send out NMEA GPS data toward the D700/D710 at the same time.

It works to parallel multiple RS232 RECEIVERS across one RS-232 source.
Trying to parallel multiple RS-232 SOURCEs across one receiver won't work so
