If you chose to add functionality to the Autonav, then you are correct. But as described in both 3rd and 4th edition, it only has an INS, an emergency battery, a screen to display microfiche or digital map (depending on generation), a method of entering coordinates for waypoints, preloaded cache locations, and a thermite charge. No mention of crypto at all. The UI is just a keypad and a couple lines of text. Other than the digital version of maps and flat panel display, nothing is beyond the 1980's level of manufacturing.
