 Original Entegra systems with the non-WAAS GNS430 navigators need to get a PFD HW and SW upgrade before they can utilize 430W or IFD440 navigators which are capable of GPS/WAAS 3D approaches like LNAV/VNAV or LPV.Navdata and Approach Charts on the MFD can be updated via the USB port on the MFD (which is not suitable for charging).With the certification of Entegra Release 9 system in April 2009, Avidyne offers dual integrated flight displays (IFD) with the FMS900w, a WAAS-capable flight management system (FMS) that utilizes Avidyne's all-digital DVX740 VHF NAV/COM radio modules and GPS722 GPS receiver modules, which eliminates the reliance on 3rd-party Garmin 430 radios.
