HUD English/Metric Input

The Head Up Display (HUD) can display the speedometer in either English (MPH) or metric (km/h) units. If the HUD control module detects a high (open) condition at terminal 7 the speedometer is displayed in English units (MPH). On vehicles with RPO Z49, terminal 7 is connected to G201 via CKT 1450 (BLK), the HUD control module detects a low (ground) condition and the speedometer is displayed in metric units (km/h).
