Summary: I was an early user of the product and had several software issues. I am happy to report that for the most part they are now resolved. My old unit was a 396 and this is much bigger and better in most ways. It took some time to get used to the touch screen in a bouncing airplane but now I would not trade it for any other instrument in the panel. I think the 3D vision is a questionable feature and find I do not use it. I like the topo map feature better.
Summary: Flying through Oregon in April and deverting around snow storms and using the 796 it suddenly without warning quit on its battery. It was connected to the aircraft plug in but still refused to work. Another brand of GPS (a back up) worked fine in the plug in and saved the day. Garmin said it needed updated and that seems to fix the problem but I do not trust it and will sell it if I can. I cannot recommend buying one.
I pinch myself every time I use this to make sure I'm not dreaming

Summary: The synthetic vision with terrain is a safety feature unparalleled in GA cockpits. Add full featured weather and XM music through the headsets and it is the cheapest and most valuable docking station avionic in the stack. I have bought two and may buy a third. I am trying to use my Foreflight in the 3rd plane I fly with it's new terrain but it isn't even close in safety. In the panel of the 414 it looks good with the 530 and MX20 but provides better information.
Summary: The 796 is much faster than my 496. I love many of the added features like synthetic vision. It has several fatal flaws however. First it crashes either by going black or freezes. If you're following fir charts this is inexcusable Second, when you take off below protected airspace, you can't see it until you're n it which means you earna violatin. Pretty bad stuff. I use a back u iPad since it cannot be trusted.
Summary: This is one awesome GPS. So bright and clear. Very easy and intuitive to operate. Touch screen much preferable to buttons. In Tidewater Virginia the terrain feature not very useful but would be in mountains. 3-D view also not very exciting. Expensive to keep up all the database, but I am glad of my purchase.
Summary: I bought this used on Amazon and I can see no difference between it and the new ones. I did notice in turbulance I must have hit something on the screen that locked it up. I tried to shut it off and couldn't and finally had to remove it from the panel and remove the battery pack for a few minutes. I reassembled, reinstalled and it's worked fine since then. Must have been "cockpit error", but I still wonder what caused it and glad I was VFR at the time.
Summary: I used the G796 for 1 week, after having 2 different G696 units in our 2 corp aircraft, now for several years. The G796 is NOT as user-friendly. Takes more motions to input/extract data, so is slower. The home screen can only display 4 data fields, compared to 12 available on the G696. The only thing I did like is detailed enroute charts, which the G696 does not, and apparently will not, have.
Summary: This is my fourth Garmin in my Bonanza. The 796 is full of potential but there are some bugs; I hope Garmin works them out. It appears that this unit was rushed to market in time for Christmas 2011 without some things getting tested or fixed first. Here is what's wrong in my opinion: 1.)Software is not ready for prime time...I am on my second 796 in two days because the first one loaded up the opening page and then went to a black screen.
