I recently installed Version 12.1 in to a friends RV-10 G3X non touch with a remote GTX 23ES remote Transponder. After installing the software I was not able to control the 23ES! The BIG RED X was present at the bottom of the screen! After many hours of troubleshooting calling and emailing Garmin. I was given the procedure reinstalling a previous version of software. In my case I just happened to have V11.8. After reinstalling 11.8 the 23ES worked just fine. No more RED X!!! To make matters worse I also updated a RV-3b with V12.1 and noted that the comm. Freq. transfer function was not working from the G3X to the GNC 255. Same thing went back to V11.8 and everything works as normal.
Lessons learned from this.
1. If it is not broke do not fix it.
2. Do not load a new software version before any cross country trip. Test it first on a short VFR flight first
3. Garmin Please remove V12.1 from your website until bugs can be fixed!
