Hi Bruce.
I have not done it, but have read that you can build a receiver for a couple hundred bucks. I think they call it a Stratux, but don't hold me to that.
I have an iPad my wife bought for me (Mini 4, wifi only) and the Garmin GDL 39 that was installed when I had the ADS-B done. It is pretty cool for flying, although I am still trying to figure out all the bells and whistles. I have had Foreflight for a while, but really haven't used it much because my Garmin 196 was much simpler and really provides about all the info I need.
