Siemens VDO RD3-01 & Blaupunkt ICDA09 Changer

[adoniram]

Hi from Athens,

I tried to install a BLAUPUNKT ICDA09 CD Changer to a 2004 Peugeot 307 Space Wagon.

The factory head unit is a Siemens VDO with the following data:

SIEMENS VDO RD3-1
VDAPVF40208280
REF: PEUGEOT
96 545 978 XT00
VDV0208280

Model No: PSARCD100-04 T0X000
Prod No : FD0104260208280

The problem is that when connecting the Changer ( blue terminal) to the head unit the AUDIO fuse (15A) is blown.

Is the Blaupunkt ICDA09 compatible with the above mentioned Head Unit or the changer itself is faulty?

Am I missing something important?
