Only the protocol conversion board with an enclosure, the supporting wiring harness must be made.

What is it?

In the early 2000s, the PSA Group (Peugeot and Citroën) used a VAN+CAN architecture in their cars. This protocol, also known as AEE2001, used the VAN bus to communicate with various comfort-related equipment and the CAN bus for communication between the BSI and the engine ECU. Around 2005, PSA transitioned to a full CAN (or CAN+CAN) architecture. The CAN+CAN system underwent several evolutions—AEE2004, AEE2007, and later AEE2010—none of which are backward compatible. This means, for example, that a head unit from a newer architecture will not work in a car with an older one. Actually AEE2004 and AEE2007 are mostly compatible and when I refer to AEE2004 below it applies to AEE2007 as well.

The goal of this project is to enable newer peripherals—mainly head units (RD4, RD43, RD45), telematics units (RT6, RCC, NAC, etc.), and multifunction displays (EMF-C, matrix display - MATT)—to function in cars using older protocols.

It supports the following conversions:

• AEE2001 ⇒ AEE2004 (VAN-CAN conversion)
• AEE2001 ⇒ AEE2010 (VAN-CAN conversion)
• AEE2004 ⇒ AEE2010 (CAN-CAN conversion)

Why did you make it?

I wanted to replace the head unit in my car with one that supports MP3 playback while retaining functionality of the original steering wheel remote stalk. I also wanted a shiny new display from newer models to work in my car. Over the years, I received many emails asking if I sold the board. I sent a few all around Europe, and now here it is :)

What makes it special?

There really isn’t any alternative for those who want to install genuine PSA parts from newer generations. By default, they simply don’t work.

Aftermarket radios always mean compromise—lost features, clunky integration, and a look that doesn’t match the car. My board lets you keep full functionality and the original factory appearance.
