This document is intended to inform dealers, technicians, parts departments, and customers of a change made to radio software to support updated Collision Mitigation, Lane Departure Warning \(LDW\), and Blind Spot Monitoring systems. If replacing the radios on the vehicles described below, the radio either needs to be built after a specific build date or have the software version verified/updated.
