With Flight 1 still working on updating their Cessna 421, I have found the perfect solution to the radio and gps.  At Flightsim.com and it may be here also, there is a file called FSgarmin.  The designer of this has done a terrific job at recreating the Garmin 500 and 430 (I think those are the numbers).  These gauges can be found with the Poormans Meridian, also.  It includes radio frequencies, etc.  I will let the images show you how cool this really is.  It takes the default FS9 GPS to a whole new level.  I plan on using these great freeware gauges on other aircraft.  There was no frame rate hits either.  My thanks to the gauge designer.  The 421 has never worked more effeciently.

Very nice indeed!
