Hi, dose anyone knows how to change US firmware to EU ? I've got uconnect 5 8.4 nav in 2022 1500 laramie GT from US with FCA-MY24.U35.26-PROD firmware. I downloaded UC5_NSE_U40.20_MAP_2025.06, unzip to pendrive but radio didn't see it. Maby there is some hack to uinstall US firmware and then the EU firmware will be install?
