Lost Communication With Navigation Display Module
Infotainment network
Generic OBD-II
Low
What it means
U0162 means the network has lost communication with the navigation display module, so the nav/display screen may go blank or stop responding. It affects the infotainment system only — there is no impact on how the engine or safety systems work. The usual cause is a wiring or connector fault, a power/ground problem, a software glitch, or a failed display module.

Can I keep driving? Yes — this only affects the navigation/display screen; the car drives and runs normally.
