The update is free of charge and will be carried out in the background. The installation will eliminate software errors for a better entertainment experience. MBUSA will conduct an OTA service campaign. A workshop visit for the customer is not required since remote software updates are automatically downloaded and installed in the customer’s vehicle. The OTA may be validated as successful on the customer’s Mercedes Me connect app under “Over-the-Air Vehicle Updates” as either “Software Update MBUX 2.4” or “Software Update Hermes 1.5 E522.8”. If the OTA is successful it will show a green “installed” and date of installation in the Over-the-Air update section.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10240250-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10240250-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10240250","components":[{"id":"electrical","name":"Electrical
