I have sent emails to info@/support@/rob@advanced-flight-systems.com over the last 2 months, requesting some thoughts on my upgrade options and am disappointed to say I have heard nothing back, so as a last resort I'll try here before going to another manufacturer.

I have an RV-7 with your AF3500EF and AF3500EM screens, ARINC module and moving map software. Also in my panel I have a TruTrak ADI-Pilot II autopilot, GNS430W, SL30, PMA-8000B and MD200-306. These were all purchased way back in 2007 and I have loved flying with them, although times are changing
