Just got back from some testing on my new GTN-650 connected to a GRT HX and most of it went perfect. It was after hours when I got back so GRT is closed. Hoping someone else with a similar setup can help with a small issue.
When I select VOR on the 650 CDI the GRT HX HSI displays the CDI info on the screen but the OBS information is not going back to the 650 so the OBS soft key is just greyed out on the 650. I have verified that the 650 is getting data from the ARINC port and the Serial port but can't find any settings on either the 650 or the GRT that involve setting up the OBS.
Any help would be appreciated.
Thanks,
Andy
