I have posted a similar thread in other forum, but unfortunately there is not many information about it.
I have a Peugeot 407 from 2009-2010, the restyling version. The car has a RNEG MyWay unit from factory like this:

As most of you know, the GPS stopped working some years ago and lately the radio signal is very weak. Apart from that, the only way to play music is by using a CD-rom
But my main concern is the can bus compatibility with the steering and clima controls. From what I have seen in the reviews, there is a Factory settings option to tell the unit which model of car you have and then it should work. Anyone has made this operation with RNEG unit and does it work well or there are other steps to be considered like reprogramming the BSI?
Many thanks in advance!
