How can i replace the normal sound system to Canton in Kodiaq 2020 and what is the expected cost?

I've never seen that offered as an after market upgrade anywhere.  I'm guessing, but probably wouldn't be anywhere near worth it in terms of improvement vs the cost and difficulty involved.

I havent seen anyone else do it except me to be honest, there may be others.

 

 

 

The work involved is massive and parts alone are over £1800, without any of the custom wiring, coding, labour or anything else.
