The rear camera guidelines may be incorrect or misaligned after the tailgate handle or the entire tailgate has been replaced (Fig. 13) on some 2020 Silverado 2500/3500 and Sierra 2500/3500 models equipped with tailgate RPOs QK1 and QT2/QT3 and infotainment system RPO IOR.
Fig. 13
The incorrect guidelines may be caused by a different rear camera angle in the replacement tailgate handle compared with the original tailgate handle. (Fig. 14) The new rear camera angle requires the infotainment system (radio) software to be updated when the tailgate handle/tailgate is replaced. (Fig. 15)

To update the infotainment system software, contact the Techline Customer Support Center (TCSC) for the correct calibration. Follow all programming guidelines when updating the software. Refer to A11 Radio: Programming and Setup in the appropriate Service Information.
