L322 Replace Head Unit but retain computer controls (2003 HSE)

Hi,
I promised myself I wouldn’t do this but…..

The majority of buttons on the standard spec head unit of my newly-acquired 2003 L322 don’t work -despite feeling like they give a positive contact -so I can’t change audio settings, control the on-board computer or even set the clock !

While it’s obviously possible to swap the head unit out for something new and shiny, is there any way to do this (ie. Are there any products which support this) and still retain (or regain) control of the computer functions and clock setting ?

Or am I looking at refurbing my dowdy original unit or swapping it for an identical one ?

It has the Single CD above it and a multi-changer (missing the cassette) in the glove box.

Thanks again for your help

Bob

Have a look at

Ah… I’m a lowly 2003 and my head unit looks like this:

That head unit is maybe the best option for upgrading as no DSP (I think) so should be fairly easy to change to whatever you want to fit, have a wander over to fullfatrr forum there will know doubt be some post's on there about it.
