Garmin 496 Connection
Could someone who has hard wired their 396 or 496 give me some pointers.
The manual isn't so clear, thus my confusion.
The wire connecter is labeled in the following manor:
Red: DC Input
Black Ground
White: Alarm
Brown: Voice (+)
Orange: Voice(-)
Yellow: Port 1 in
Blue: Port 1 out
Green: Port 2 in
Violet: Port 2 out
Red & Black - I have those down, not a big problem. One question, the positive (red) wire has a fuse on it. Since I am wiring this to a breaker, do I still need the fuse?
Alarm: Is this for a warning light or is it a warning tone?
Brown & Orange: Is this a voice warning, such as the terrain warning. Thus it sounds like it can be wired into my intercom.
Yellow & Blue: ?
Green & Violet: ?
My -9 will not have an autopilot (at this time) but it does have a Dynon D100.
Here is a diagram of how I have my electronics wired:

This was drawn before I received the Garmin and I had no idea how that would connect into my system.
Also, how do you connect the XM radio into the system.
Thanks for the help!

gps 396 & 496
The garmin 396 & 496 has a plug for the audio (music) out put,
looks like a hole in your ipod for headphones, buy or build a plug
that is wired to your intercom input..
Red: DC Input = Aircraft Power (mine is on the dynon d-180 buss)
Black Ground = Common ground (share with the dynon ground per dynon)
White: Alarm = audio to intercom system, not totally sure of this one
audo or visual but I think this is correct and also the alarm will output
from the music plug also.. I think the visual is on the 496 screen
Brown: Voice (+) per garmin (only for auto and boating use)
Orange: Voice(-) " "
Yellow: Port 1 in = I am not using it (not sure what this is for) anyone ?
Blue: Port 1 out= to Autopilot
Green: Port 2 in= I am not using it see above
Violet: Port 2 out = serial buss see below the updated pin out
this one on mine will go to pin 19 on the 37 pin on my d-180 ,
if you only have the efis then its pin 22 on the 25 pin plug, see below
Depending on the number and types of Dynon units you own, you have several options for connecting a GPS unit and/or Garmin/Apollo SL30 to your Dynon system. The GPS can be used as a source for both the HSI and Fuel pages. The SL30 can be used as a VOR or localizer source for the HSI. If you wish to connect a GPS and/or SL30 to your Dynon system, read the section below which corresponds to your set of Dynon products.
To fully use the GPS-related features on your EFIS and/or EMS, your GPS must output the following NMEA sentences in its serial stream: $GPRMC, $GPRMB, $GPGGA, $GPBOD, and $GPAPB. All of these connection schemes assume that the external devices share a common ground with the Dynon product(s). If your GPS is battery powered, and not normally connected to aircraft ground, you must connect the ground pin on its serial output to a ground common to the EFIS or EMS that your GPS is connected to (e.g., pin 9 on the EFIS DB25, or pin 16 on the EMS DB37).
When a Dynon product is connected to a GPS, it will synchronize its Zulu clock to that output by the GPS.
If you own only an EFIS-D10A or EFIS-D100:
Hook the GPS or SL30 transmit line into pin 22. This is the same Serial RX line that is used for firmware updates. You'll need a way to disconnect this when you hook up a PC.
If you have both a GPS unit and an SL 30, you'll need to hook the two transmit lines to a switch and use this switch to decide which one you want displayed on the HSI. The HSI will auto-detect the switch being changed and will change modes automatically.
If you own an EMS-D10 or EMS-D120:
Hook the GPS transmit line into the EMS pin 19 on the D-37 connector. This is labeled "Fadec RX." This connection will give you range, MPG, etc. No point in hooking up an SL 30 since that only sources info for the HSI display which requires an EFIS. No need to break this connection when doing PC updates.
If you own an EMS AND an EFIS:
Hook the GPS or SL30 transmit line into the EMS pin 19 on the D-37 connector. This is labeled "Fadec RX." This will share the data between the EMS and EFIS and allow you to display an HSI on either product, as well as do EMS economy displays.
If you have a GPS and an SL 30, hook the GPS up as above. Hook the SL 30 to pin 22 on the EFIS. This will allow you to use the "NAVSRC" button on the HSI to flip between inputs. The only tradeoff here is that you can only display a GPS HSI on the EMS. You can see either the SL 30 or GPS on the EFIS. You'll need to disconnect the SL 30 from the EFIS when doing software updates.
Alternatley, you can use a switch into the EMS which will allow you to see both the SL 30 and GPS on both the EFIS and EMS, but you will only be able to see one at a time.
If you own a D180:
Hook the SL 30 unit to pin 22 on the EFIS (vertical D-25) and the GPS to pin 19 on the D-37. You can display either source on the HSI with the "NAVSRC" button. You'll need to disconnect the SL 30 from the EFIS when doing software updates.
If you own a D180 AND an EFIS:
Hook the SL 30 unit to pin 22 on the EFIS (vertical D-25) and the GPS to pin 19 on the D-37. You can display either source on the HSI with the "NAVSRC" button, and you can display either on the standlone EFIS as well. You'll need to disconnect the SL 30 from the EFIS when doing software updates.
hope this helps and is not too long..
Danny..

Garmin 496 Connection
Bill:
According to Garmin Tech Support,the orange and brown wires are for voice output to the car speaker for use when navigating in your car. Don't hook up the voice output to your intercom; you'll likely do some damage. Normal audio output for terrain and XM Radio on the 396/496 is via the 1/8" audio plug on the back of the unit.

Agree, additional
Bill, The COM1 output is for serial GPS signal such as to an autopilot. On the 496, the COM2 is for the weather, according to Garmin when I checked this week. That pair should not be used. If you use COM1 you have to configure it. Go to Setup, Interface tab. If you select an NMEA option you can press Menu to go to advanced NMEA for further details. The 296 had a COM2 output configuration but the 496 doesn't because they took it for the WX. I think the documentation with the XM antenna gives more info on hook up for that (mini-USB, I think). The tag on the power cable gives detail on which wire goes where. Also, in case nobody said it already, you can drive multiple devices with the COM1 by forking the wire. It's not unusual to see three devices driven off that wire (blue on mine).
Call while I'm in the hangar if you need to go over any details; you've got the times and codes for that!

Danny (and others), thank you for your replies!
Nothing is ever as easy as it seams.
My panel has a Dynon D100 EFIS and a D10 EMS (Bussed together), Sigtronics stereo intercom, and iCOM radio. (Along with the Garmin 496.) Simple D/N VFR panel.
Thus, the section I included in the quote above sounds like the way for me to go.
Thanks again for the help!

garman 496
I was wondering, what are those imput for on the garmin, data imput
it has two on there, I have the outputs one going to the dynon and
the other output for the autopilot but I don't see what the 2 imputs
are for.. anyone know ?
update, I just figured out the 496 only has one output, to drive the autopilot
and the dynon, and I am guessing the inputs one being for the traffic info
from a Garmin 330-S transponder, what could the other one be used for ?

I finally got around to calling Garmin today.
The connections are very simple.
Red and Black are power. (Duh!)
Blue: Port 1 out goes to the Dynon or auto pilot.
The rest are used in auto or boat mode only.
The audio aka XM Radio comes from the 1/8" jack on the back of the unit.
That sure makes wiring it much easier.
Thanks for all the help.

If you have a Garmin 430/530 you can transfer a flight plan and waypoints (including IFR approach points etc.) from the panel mount to the 496.

I have a 430 and would like to cross transfer flight plans. Which wires would be used for this. My AP is connected to the analog output of the 430, so I don't need to connect it to the 496.
Also about the audio warnings; if I use the music input to the audio panel and am not wanting to listen to the music, won't I miss the warnings? Is the white (alarm) wire going to provide this same audio? Can it just be hooked into the non-selectable audio line on the audio panel (PM6000M)? I already have my engine monitor and the AOA hooked to this input. The wires are just hooked to gether and it seems to work fine. Can I hook a third wire directly to this same pin?

See here on connecting the 430 to your portable 496. Pin number will be different from the depicted 195.
By AP do you mean audio panel or auto pilot? I'm assuming audio panel. Your PMA 6000 has many inputs and will "blank" the music input during radio transmissions and warnings as long as it is on the music input line. If you put the 496 music on a regular audio input line, it will not "blank" during transmissions and warnings. Only one audio input per line.
