Page 18: Overview
System at a Glance Overview The GPS 175 and GNX 375 are the first 2” by 6.25” panel mount navigators to employ full color capacitive touchscreen technology. The GPS 175 is a TSO-C146e compliant GPS/WAAS navigator with en route, terminal, and precision/non-precision approach capabilities. The GNX 375 combines the functionality of the GPS 175 with a TSO-C112e (Level 2els, Class 1) compliant mode S transponder.
