The Peugeot Boxer shares a common platform with the Fiat Ducato

Fiat Ducato

The fourth generation Ducato/Jumper/Relay/Boxer was announced in May 2014.

Wiring Information (may relate to Ducato only)

If the vehicle has phone buttons on the steering wheel and not on the radio, it will have an external bluetooth module. It is located directly underneath the factory radio, which is a double din face with a single din frame taking up the upper portion of the vehicles double din cage.

The options are using an aftermarket single din framed double din radio, or as I found out, return to Fiat and they will do a firmware update on the ECU to tell the vehicle to no longer look for the bluetooth module and you can thereafter remove the module. If you just remove the module, the odometer will continue to flash.

The 2021 touchscreen Nav is a Daiichi unit and appears to have the same connector as the standard unit.
