Sounds like the same problem i had with our Scenic.
It proved in the end to be the display which was at fault,without that working you cannot enter the code.
As you say the aftermarket radio works (which i assume does not need the display) we can safely say the iso connectors have the correct conditions.
take a look at this link
Connnector C1 is the display
With a meter check for power and data......or lift the top off the dash and check behind the display.
Hope this helps.
