I have had a 296 for about 2 months now.
Great unit. You can download your flights from it to your PC and it automatically logs them with all the details such as flight hours, landings, destinations, x-country time, miles flown, max speed and alt. This is a very nice feature as your logbook is always accurate and you don't forget to log any flights even if you don't log them right after.
The unit is very easy use as all Garmins are. I did not have to read the instruction manual and found all the different features quite easily.
It comes with a small built in attenna that you can remove and replace with a remote one that fits on your dashboard, so you get great reception even if you mount it on your yoke.
It automatically starts up when you turn on the master and turns off when you shut the master off even with batteries inside. It turns off 30 secs after shutting down your master so it is a logic feature and not just it cutting out when the aircraft power is off. That gives you 30 secs to decide if you want to keep in on for some reason like checking your flight information.
The terrain feature in nice as well.
Excellent all round unit but the dealers have all fixed the price so it is hard to get one below $1699
