Corvette HMI 2.0 to HMI 2.5 upgrade: USA-to-Europe conversion

One method is to replace the HMI and radio module. The used HMI and radio will be locked to the other vehicle. The file below will remove the theft lock from the used, secondhand European market HMI and radio module using the DPS software tool.

1. Purchase a used, functioning HMI 2.5 module from a website like eBay in Europe. (Any HMI 2.5 module with a GPS antenna port connector taken from a GM European-market vehicle will work. One taken from a 2019 or later vehicle is best, as it should already have the latest maps installed.)

2. You must also upgrade the radio module to one taken from a European-market vehicle that had the HMI 2.5 module (2016 or later vehicle).

3. You must replace the dual USB port with a single USB port for wired Apple CarPlay or Android Auto to work.

4. You must program the HMI via the GM SPS service or DPS, according to your vehicle's specs (The used HMI 2.5 module will have the previous vehicle's settings installed, for example, the vehicle's boot up logo etc). You will need to source a 2016-2020 Corvette VIN taken from a European-market Corvette, then use that VIN to program the HMI module via GM SPS service to regain the Corvette's boot-up logo, etc.) I have the HMI 2.5 premade DPS file for the USA Corvette, but not for the European-market Corvette.

The GM DPS file, which will remove the theft lock from the used European-market HMI 2.5 and radio module.

This file will restore the Corvette's boot-up logo and activate video in motion. The file was modified for the USA Corvette. The file will install fine on the European market HMI 2.5 module, but I don't know if it will work properly with the American market Corvette vehicle that has a European market HMI 2.5 module installed.
