GPS Cerfitification Setting for Trig / 430W

I installed my 430W this weekend and need to finish up the GRT/Trig programming. I need to put a certification setting into the config. I assume this will set the SDA / SIL and other variables. It offers me A through D, if I recall. I am guessing from my research that the 430W would be a "C" but hoping others have done this and know for sure.

Bob, I believe your setup is the same. What did you use for this setting?

Feel free to call me during the day today to verify on my 182 with this setup, but I also think it is C.
 
"C" is correct. Reference here is from the Skyview Install Manual, pg 11-19 and 11-20.
"GARMIN ADS-B/ADS-B+: Garmin GNS 400W/500W series (WAAS) or Garmin GTN series, both with appropriate firmware updates as designated by Garmin, connected directly to SV-XPNDR-261/262 pin 3, transmitting at 9600 baud in ?ADS-B+ OUT? or "ADS-B" format. "ADS-B" format only works with SV-XPNDR-261/262 firmware 2.02 and above. "ADS-B+" format requires SV-XPNDR-261/262 version 2.06 or later. With 2.06 or later firmware the format in use will be auto-detected. The original Garmin ADS-B format is not compliant for use after 2020, and may cause compliance failures in the FAA's ADS-B monitoring system, but is acceptable to use until 2020. See SV-XPNDR-261/262 Firmware Updates below for more information about updating the SV-XPNDR-261/262 firmware. Using this setting causes the SV-XPNDR-261/262 to transmit the following ADS-B performance parameters:
 SDA: 2 (Level C integrity) SIL: 3 NACp: Sent from GPS to transponder. Refer to GPS documentation. NIC: Sent from GPS to transponder. Refer to GPS documentation. NACv: 1 (10m/s accuracy)
o TRIG ADS-B (TN70): Must be connected directly to SV-XPNDR-261/262 pin 3, transmitting at 19200 baud. This device is only supported in SV-XPNDR-261/262 version 2.06 or later. See SV-XPNDR-261/262 Firmware Updates below for more information about updating the SV-XPNDR-261/262 firmware. Using this setting causes the SV-XPNDR-261/262 to transmit the following ADS-B performance parameters:
 SDA: 2 (Level C integrity) SIL: 3 NACp: Sent from GPS to transponder. Refer to GPS documentation. NIC: Sent from GPS to transponder. Refer to GPS documentation. NACv: 1 (10m/s accuracy)"
