CLI alternative to PSA (Peugeot / Citroën / DS / Opel) infotainment system update (NAC / RCC firmware and navigation maps), hopefully more robust.

psa-update offers mostly the same features as the official firmware/map update application proposed by the car vendor, except that it does not format the USB device that has to be used to upload the firmware/map update to the car. Updates are exclusively downloaded from the official PSA site.

Features:

• Download updates of RCC / NAC firmwares, and navigation maps (NAC only)
• Resume downloads in case of failure
• Prepares USB flash drive for car infotainment system update
• Lightweight self-contained executable that can run on multiple platforms: Windows, Linux, MacOS

The command line executable can be invoked in a terminal:

$ psa-update

This will interactively ask for vehicle VIN, check for available NAC/RCC/map updates, and extract updates to a USB flash drive.

Once copied to the USB drive, the update can be applied on the infotainment system following PSA instructions. For example for Peugeot:

• RCC instructions
• NAC instructions

On Linux, OpenSSL is required. On Windows and MacOS, nothing is required, the operating system TLS framework is used.

Binaries are available for Windows (x86-64), Linux (x86-64) and MacOS (x86-64 and AArch64/ARM64) in the releases section. To install, simply download and extract the psa-update executable. For other platforms the project can be built from source code (see below).

To build and run from source code using stable rust compiler toolchain (version 1.81+):

$ git clone https://github.com/zeld/psa-update.git
$ cargo run

Download is possible behind a proxy provided the http_proxy and https_proxy environment variables are correctly set. In a Linux or MacOS shell:

export http_proxy=<host>:<port>
export https_proxy=<host>:<port>

In a Windows CMD prompt:

SET http_proxy=<host>:<port>
SET https_proxy=<host>:<port>

Logging can be enabled using the RUST_LOG variable. For example to enable debug log level:

RUST_LOG="debug" ./psa-update
