Edit 11 Feb 2009 by Breister - We have two confirmations from people that they have gotten all functionality working as expected with v2.0 of the Garmin software or above.  Version 2.3 of the software is the latest (and probably final) version, and you should GET THE UPGRADE!!!  It is FREE - you just need to arrange with your local Garmin rep to get it done.  Takes about 2-3 hours, and they provide you a new antenna which, together with the software, finally provides full WAAS / GPSS functionality.
  
Edit 22 Dec 2008 by Breister - I have version 2.0 of the GNS 480 software / v5.0 Dynon and NO combination of settings works either for Nav or for GPS using ARINC.  Serial works for GPS; there might be a setting which would work for Nav too, but I'm using the other serial line for my 496 and hoping for an ARINC fix.  In a discussion with a Garmin field repair tech he recommended some settings (shown in table below) which do not exist in my version of the GNS 480 software.  v 2.3 has JUST been released, and requires taking the aircraft to a Garmin authorized repair agent to do the software update and to replace the antenna (the antenna will be provided by Garmin free of charge; expect up to 3 hours labor to complete the upgrade).

On the GNS 480 side, only Input #2 accepts EFIS command.  The HS34 has two sets of pins which will output ARINC, but that is only for convenience because both pairs output the exact same thing so you can use HS34 ARINC output #1 or #2.  The only output setting is "Enable."
 
 
So, I will provide an update on this board once I get the GNS 480 updated.

Edit 11 Feb 2009 by Breister - We have two confirmations from people that they have gotten all functionality working as expected with v2.0 of the Garmin software or above. Version 2.3 of the software is the latest (and probably final) version, and you should GET THE UPGRADE!!! It is FREE - you just need to arrange with your local Garmin rep to get it done. Takes about 2-3 hours, and they provide you a new antenna which, together with the software, finally provides full WAAS / GPSS functionality.

On the GNS 480 side, only Input #2 accepts EFIS command. The HS34 has two sets of pins which will output ARINC, but that is only for convenience because both pairs output the exact same thing so you can use HS34 ARINC output #1 or #2. The only output setting is "Enable."

P5 (78 Pin) 4 ARINC 429 Tx Channel 1A Gamma 429 / Low Fem D25 23 ARINC 429 RX 1-A Gama GPS / Low GPS HSI Data - not functioning with v2.1
P5 (78 Pin) 24 ARINC 429 Tx Channel 1B Gamma 429 / Low Fem D25 11 ARINC 429 RX 1-B Gama GPS / Low GPS HSI Data - not functioning with v2.1

P5 (78 Pin) 28 ARINC 429 Input Channel 2B EFIS Sys 1 / Low Fem D25 12 ARINC 429 Tx 2B Output "On" Should provide Nav course setting back to 480 (Note: Same output as Tx 1)
P5 (78 Pin) 30 Serial #8 (use only if you don't have HS34) Alt Enc / 1200 Vertical Fem D25 (D180 - NOT HS34!!!) 13 Serial Output Alt Encoder / Format 1 This is NOT necessary - ARINC provides baro from HS34 toCNX80/GNS480
P1 (Main) 4 RS232 RxD1 (Input) SL 30 Male D25 14 Serial 1 Tx SL 30 Command Unconfirmed if this does anything
P1 (Main) 5 RS232 TxD1 (Output) MAPCOM 9600 Male D25 1 Serial 1 Rx Aviation 9600 Provides GPS Course - CONFIRMED

Final thought: May wish to keep the serial connection for GPS even if the ARINC proves to work with v2.3, as this would provide a backup connection in the unlikely event that the wires somehow failed in flight. This can be enabled / disabled in flight in the HSI setup.
