FS2004 Cessna Skyhawk 172SP IFR Panel Avionics Upgrade. This modification upgrades the default 172 IFR panel avionics to a Garmin 430/530 setup with the Garmin STX330 transponder. Also included is a CD radio that allows you to relax on those long flights with up to 12 song of your choice. By Chase Barnett.
