Sorry, I do not have first hand experience with this kit. However, at first glance, it appears to be an add on and not a stand alone EFI solution. The display is not a PFD. I would much prefer having all that info on the PFDs (plus an MFD) like in the Garmin 3000 or 5000 for example. I saw on the Garmin site that they now offer G5000 retrofits for, for example, the XL(S) and the Beechjet/Hawker 400. That would be a very nice, albeit probably much more expensive , solution. The Garmin Connext weather is also very nice to have. It gets you amongst other things downloaded radar pictures as well as lightning information. What model light jet are we talking here?
