I've got a TruTrak ADI II connected to a GNS430 (non-WAAS). Normally they communicate fine.
But I?m having occasional trouble switching the ADI II between the TRACK and NAV modes. Because the non-waas 430 does not fly the holds and procedure turns, I need to switch to TRACK to fly those ? and then back to NAV when I head inbound.
After using the NAV to fly to the intial fix, I switch to TRACK to fly the hold. When I tell the 430 that we?re going to the runway (and I get a magenta line), sometimes I can switch back to NAV ? and sometimes I cannot.
I?ve checked for a bad connection on the ground. I brought up the 430 to the Instrument Panel Self-Test page (pressing ENT only once). I pushed the ADI right button twice and got the NAV to come on. Then I wiggled the RS232 wire between the 430 and the ADI at each unit - and the NAV light was rock-solid. So it doesn't look like I've got a short.
When I call both TruTrak and Garmin, they are suspicious of the others box. So I?m in the middle.
If anyone has an ADI II to GNS430 (non-WAAS) configuration, I?d appreciate knowing if you have similar problems ? or if you can reliably switch between NAV and TRACK.
Thanks.
