full-color moving map display,
Power/Home
button, dual concentric rotary knob with push entry, SD card
slot, and photocell. The internal AHRS sensor cannot be used to drive anything other than the display of
attitude on a non-certified PED. The built-in Bluetooth allows for flight plan I/O and GPS position
interface with a PED (Database Concierge only available through Flight Stream 510). The GPS 175 is
capable of providing TSO-C146e compliant GPS/WAAS navigation for en route, terminal, non-precision
and precision capabilities (LPV) when interfaced with a CDI. The GPS 175 is also a certified ADS-B Out
position source. The bezel of the GPS 175 is 2 inches x 6.25 inches and is designed to fit in the same
location as older 2-inch avionics, such as GNC 255 or GTR 225.
