Aero-News.net has a short article on the GDU-375 MFD release.
The MFD and PFD for the G300 will be essentially the same hardware. Connecting an ADAHRS and EIS, magnetometer and temperature probe to a GDU-370 will give PFD functionality. The GDU-370 is the same thing as the GDU-375 but without the XM satellite radio.
