Don't count out the Dynon Skyview; in my opinion it is still a great option and they offer their Fast-Trak installation options which include accessory packages and mountings and all interconnecting wiring harnesses. I have been loving mine for 10 years now and not only will it do anything Garmin can do, but all (and I mean all) software/firmware/database upgrades are totally free. This is a big deal when you consider upgraded soft/firm ware comes out several times a year.
