Blaupunkt HEIDELBERG CD51 Operating Guide

25

In addition to the CD changer, you can
also connect up a different external au-
dio source with a line output. Such
sources can be, for example, portable
CD players, minidisc players or MP3
players.
If there is no CD changer connected to
your unit, two external audio souces can
be hooked up.
The AUX output has to be switched on
in the install menu.
To connect up an external audio source,
you will need an adapter cable, obtain-
able from any authorised Blaupunkt
dealer.
