I've been using Foreflight but know that the choices are limited to Stratus but its available now at least. Will the XGPS170 work with FF or is it doomed to remain vapor ware? They claimed late September and have not updated the website or sent out any updates but it will have tis-b as well. Garmin has their over priced gdl-39 and buggy garmin pilot app. Wing X promises more options but is more costly than Foreflight for the same thing. So wait for xgps and hope it works with Foreflight? Any other options out there? Reviews? Thoughts? What am I missing?
