Pilots can access the info on Garmin Pilot and ForeFlight, along with portables such as the aera 795, thanks to wireless streaming. The transponder comes in a standard 1.65-inch form, allowing it to easily take the place of existing transponders in the panel, and has a digital display that features pressure altitude and a timer. The GTX 345 sells for $4,995 without WAAS and $5,795 with it. Garmin also offers an ADS-B Out-only version of the product, the GTX 335, which also comes with the WAAS option.
