C5 Stereo Upgrade & display functions

[robella]

Hi everyone

As of today, I now own my first Citroen! Got myself a lovely C5 Estate 1.6VTR 2005.

I wanted you advice please on changing the stereo. I have my own JVC which I was going to get installed. But I notice that the factory stereo includes functionality to change the clock and other personalisation settings via the dashboard display.

If I remove the factory fitted stereo - will this functionality be lost as well? How would I change the clock time for example?

Help me out if you can!

Cheers
