Hi everyone, I’m looking for some advice on updating the infotainment system in my 2018 Škoda Superb. I believe I have an MIB2 High Columbus system, and I’d like to update it to the latest firmware to improve performance and fix some issues (like the SW Train version showing as dashes). I’d really appreciate your help in choosing the right firmware and guiding me through the process. My System DetailsHere are the details from my infotainment system: Part Number: 5Q0035840C Software Version: H29.319.29.3.STD2Plus_EU SW MU Version: 0468 SW Train Version: --- (it only shows dashes) HMI Software: H29.319.29.3.STD2Plus_EU Skin Short: SKODA_STD_Skin_C_80_S-STD2PLUS_EU-3 Skin SPF Filename: Skoda_STD_Skin_C_80_S.spf My system is an MIB2 High Columbus with an 8-inch screen, and I’m pretty sure it supports SmartLink (Android Auto/Apple CarPlay) and navigation. I’m not sure if I have a Canton sound system, but I’ll check with VCDS later today. My GoalI want to update my system to the latest firmware to improve stability, SmartLink compatibility, and overall performance. I’ve heard that MHI2_ER_SKG11_K3343 (SW MU 1433) might be the latest version for my system, but I’m not sure if it’s compatible or how to proceed safely due to the version gap (from SW MU 0468 to 1433). My QuestionsWhat is the latest firmware version for my MIB2 High Columbus (5Q0035840C)? Is MHI2_ER_SKG11_K3343 the right choice, or is there a newer version I should consider? or maybe the SKG11 is wrong? How should I update safely? I’ve read that a direct update might cause a "Train is locked" error due to the version gap. Should I use intermediate firmware versions, and if so, which ones do you recommend? Where can I download the firmware? I’ve checked the Škoda Update Portal, but I’m not sure if the files I need are available. Does anyone have a reliable source? Are there any risks I should be aware of? For example, will SmartLink or navigation need reactivation after the update? If I have a Canton sound system, will I need to adjust anything afterward? I am thankful for any help. BR Darko
