After nearly a nine-year production run, Garmin announced a replacement for the G600/G500 retrofit flight display systems and it's called the TXi series. The TXi line includes the G500 TXi, the G600 TXi and the G700 TXi, the latter of which is intended for Part 23 and Part 25 aircraft. The touchscreen TXi systems (which also have function knobs for users not sold on a total touch interface) are available in three display configurations, including two versions of 7-inch displays in portrait and landscape orientation. The systems have internal backup GPS capability and can be paired with an optional PFD control head for adjusting the heading bug, baro setting and altitude bug separate from the display, to name a few functions.
