We did it in January.
- Great upgrade. The difference in resolution is very nice.
- I like the synthetic vision.
- You will have an internal GPS in each unit.
- Much brighter in than the WS.
- Engine instruments along the bottom of the PFD.
- It was a fairly easy install, though not quite plug-n-play like they advertise. The hole in your panel will work fine, but the bolt holes don't match, so you will have to move your nutplates or whatever is holding your current WS system in. I'm sure they had a good reason for changing the bolt holes, but it sure would have made it easier if they had matched them up for a true plug-n-play replacement.
- The serial ports are in a different position on the back of the units, so you may have to adjust some of your wiring. Mine ended up being just a bit short, but I was able to make it work. Otherwise, it is a direct plug and play.
- Easy set-up by copying your old settings and importing them into the new units.
- IF you have an old transponder, like we did, you may need a grey code adapter to get your EX talking to your transponder. We have a Garmin 320A and without the grey code adapter, we could not transmit mode C. GRT was awesome about making me a grey code adapter to fix the problem and it worked as advertised. Not a difficult instal, but it took a couple of hours.
- GRT's customer support was outstanding. I love these guys.
Overall: A very worthwhile upgrade. The attached picture does not do it justice because we don't have many hills around here to show off the synthetic vision and the digital camera made the picture look pixelated. It's much sharper in real life.
