RD45 bass & treble

[Abbe]

Hi!

I did a swap of a RD4 to a RD45 and a newer screen in my Citroen C5 X7 -09. It was VIN coded by the seller. The screen i bought from a scrapyard. I have sound, bluetooth and everything seems to work but no adjustment for bass & treble (which would be very nice since i also replaced the useless plastic speakers and installed a small Kicker 200.4) only the presets "techno", "jazz" and so on. Went into Diagbox but find nothing obviosly wrong. There are no options för bass & treble as there is for example fader.
Tried to "uninstall RD4" but Diagbox fails, tried to "Install RD45" but Diagbox fails. In global test Diagbox recognizes the radio as RD45 but I can see that an option RD4 i presen in BSI. After my fiddeling everything is ad before exept the "Audio Meny" i greyed in the MDF...
How do i get bass and treble adjustment...!?

Regards
Abbe

I would suggest a visit to a specialist but as you have not filled in your location in your profile it is not possible to suggest anywhere.

I've had the exact same problem in the past. Try this,

- Set the Preset to "None".

The Bass and Treble controls will appear.

Unlike the RD4, you can't have both presets and tone controls at the same time.

Oh my god what a simple and irritating solution after a couple of hours in Diagbox!
Fixed, tank you!!
