INSTALLATION SERVICE: Illustrated description where what needs to be in the series shaft "edit" (Hab expanded the series fascia around the radio and climate control system and processed with wood rasp and fine MultiMaster).
If you have some skill you're done in 30 minutes. If you want to have it in greater detail simply "Googling".
As someone has taken the trouble and have the process with pictures described super.
To remove the radio series we still need an extraction tool separately. Gibts also in the network.
Or just ask the friendly dealer. The machts usually free.
