Welcome one and all.
Feel free to ask any questions for help in the comments section.
Here you will find information and files for upgrading your HMI v2 to the HMI v2.5 or replacing your HMI module with a used part.
Upgrading from HMI v2.0 to HMI v2.5 will enable you to have Apple CarPlay, Android Auto, better SAT-NAV maps, play videos and faster touch reaction from your touch screen.
Most of GM's electronic modules car parts are security locked to a specific car via the car's VIN number.
To install used car parts and have them functioning, you first need to program your vehicle's VIN number into the module.
When upgrading from the HMI v2.0 to the HMI v2.5, you must also upgrade the radio module. You can bypass the radio module upgrade by updating the radio module firmware to v2.5 specs, (if you update the radio module firmware you no not need to replace it)
The radio module upgrade firmware can be found below.
You will also need to replace your vehicle's double USB port with a single USB port to get the Apple CarPlay working.
See the below photos.
The items you will need for removing the theft lock from the HMI module:
- A copy of GM DPS software, preferably V4.44.
- My custom DPS HMI vin change file
- A compatible GM diagnostic interface example: VXDIAG Nano, Drew tech mongoose GM2 pro etc., (all diagnostic interface that works with GM's SPS will work with GM's DPS software.
