Bad day

[Paul Z]

I had a bad day at the airport last week. The man I share a hanger with, gave the key to an A&P to work on his plane. When I went out I found my door open, which I never leave open. I got in and found the master switch was left on, battery dead. I pulled the battery, took it home to recharge. I went back to install the battery, and go fly and I got this message on my Advanced Flight 3500 system. I called Advanced Flight it seems as if they believe it killed the AHRS Communications Card. I need to pull it and get it repaired for about $1000, or get an Advanced Flight 5600 or 5800 upgrade. I like the synthetic vision, and the maps, but it's not cheap. 😂 😃 😡 😉
I was thinking of upgrading, and making it 2020 compliant. My IA is more than willing to do the upgrade. I was thinking AF 5600 or AF 5800, AF ADSB, AF Mode S Teansponder. Any recommendations?

Ahh finally the right picture
