1.4.�External�CD�player
1.4.1.�Introduction
A�CD/DVD�drive�is�not�integrated�into�the�new�Head�Unit�High�3.�When�ordering�the�vehicle,�the
customer�can�also�order�the�optional�equipment�"Preparation�for�external�CD�player�(SA65A)".�In
doing�so,�it�is�important�to�bear�in�mind�that�this�is�only�the�preparation�of�the�vehicle�wiring�harness
used�to�connect�the�external�CD�player.�The�external�CD�player�is�available�as�an�optional�accessory.
It�is�not�possible�subsequently�to�retrofit�the�optional�equipment�"Preparation�for�external�CD�player
(SA65A)"�to�the�vehicle.
When�purchasing�the�optional�accessories,�the�frame�and�the�CD�player�are�installed�in�the�vehicle�at
the�workshop.�The�CD�player�is�automatically�detected�by�the�head�unit�once�the�vehicle�has�gone�to
sleep.�Coding�is�therefore�also�not�necessary.
The�external�CD�player�is�installed�in�the�glove�compartment.
Audio�data�read�by�the�CD�player�is�transferred�to�the�head�unit�via�a�USB�connection�or�ID3�tags.
The�head�unit�processes�the�data�and�forwards�it�to�the�Receiver�Audio�Module,�which�has�the�task�of
playing�the�music�back�via�the�loudspeakers.
The�CD�player�supports�the�following�file�formats,�among�others:
• MP3
• M4A
• FLAC
