Garmin GDU375 Reverted Back To Factory Default Settings

[T Hunter]

I made the mistake of starting my Carbon Cub #169 with the avionics switch on. Turns out that was a very bad move. It apparently caused voltage issues with the Garmin GDU 375, and it reverted back to Garmin factory out of box settings. I lost all history and post install settings. I have the performance VFR panel with EI fuel flow and EI engine monitor. Becker com and transponder, and a Garmin GDL39R for ADSB in. I'm showing an RF antenna failure message on the transponder too.I was able to work with Garmin to get back the weight and balance page and he GDL39 is talking again on RS232 port two. Anyone had a similar issue? I sent an e-mail to Jon and Stan too at CubCrafters in hopes of finding the factory settings to bring it all back.

I think the same has happened to my aircraft. Does anyone have some detailed simple instructions on how to connect the com to the GDU and customize all the settings?
