This tutorial illustrates how to update your 2014 Insignia-A/Buick Regal 8-inches instrument cluster to the last firmware update. This update will gives better graphics and features, with minor differences compared to the later 2019 Insignia-B instrument cluster graphics. Before you attempt to upgrade the instrument cluster/IPC firmware you need to take into account 3 important things.
- You need to already have a Buildrecord.txt file with all your car’s RPO codes in the list.
- DTC error may pop up on your IPC screen and you will need to deactivate them manually by editing IPC’s XMLfile.xml file as explained in the other IPC tutorials.
- Make sure you have a copy of your original IPC firmware, DPS calibration and XLM files just incase you need to revert the IPC back to stock.
