# Service bulletin L\-TT\-0293\-20 Rev

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

TT: NOTE: This document ONLY applies to 2020 ES \& 2020 NX vehicles built before 10/01/2019. \(Vehicles built after that date use AT\&T WiFi, not Verizon\) Head unit telematics services become inoperative after DCM replacement and activation if the guest has an ACTIVE Verizon Wi\-Fi pre\-paid subscription. Head unit services include Wi\-Fi, Destination Assist, Dynamic Navigation, and Dynamic Voice Recognition. Verizon is not able to transfer the pre\-paid subscription to the new DCM automatically. As a result, the guest is unable to use their head unit telematics services. At this time if the DCM is replaced and activated before confirming the guests Wi\-Fi subscription status, this may require Verizon?s IT to perform a manual fix on the customer?s account. To simplify the diagnosis and prevent the unnecessary replacement of parts, please refer to the procedure below. NOTE: This Tech Tip does not apply if the guest is currently under their Wi\-Fi trial.
