I was doing a little reading about this, since my club plane actually has a
430 and 195 but I've never bothered to hook them up.

This is from the 195 manual, and applies to all subsequent 19x, 29x units as
well:

"Aviation In/No Out is a proprietary interface for connection to a GARMIN
panel-mounted GPS receiver. With this selection, and a two-wire connection
to the panel-mounted GPS receiver, any GOTO or route selection is
automatically displayed on the GPSMAP 195. This eliminates the need to
enter the data into both units."


Interestingly, the 396 manual claims that the 396 can display, in addition
to XM Weather, information from the following external devices:

- TIS (traffic) alerts from Mode S transponders
- Sonar plots from the garmin sonar products (for use in Marine mode,
obviously)
- DGPS (I've never heard of this before, but apparently it's a technology
similar to WAAS for marine use)

And, the 396 can also apparently push VHF COMM frequencies to SL30 and SL40
radios.

Well the 430/530 are extremely popular. It is hard for me to imagine why
a 430/530 owner would choose a portable GPS model that will not interface
with the 430/530. The parts/labor to interface the 430/530 to the 396
cost perhaps 2% of the total cost of the 430/530 installation. I am not
saying all 430/530 owners need a 396 but it is inconceivable to me for
someone to install such an IFR GPS and then not be willing to pay $400
for a used 195 and $150 to an avionics shop to interface the two. That
is a bargain if ever I saw one in aviation.

I have never heard of interfacing a 195 to a 530. What information is
shared?
