I'm looking through the GNS 430 install manual and I see two pairs of audio outputs on P4001 (the big connector). They are labelled "AUDIO 1 HI (pin 37) / AUDIO 1 LO" (pin 38) and "AUDIO 2 HI" (pin 52) / AUDIO 2 LO" (pin 53)
These are not the COM audio or intercom (those are on P4002) or the NAV audio (on P4001). I think they might be audio alerting outputs? Would these be for the terrain option, or does it alert at minimums or something else?
I cannot find those 4 pins used on any of the wiring diagrams.
Thanks for any info,
