hey guys dunno if any of you audio gods can help me but hear we go....

I installed the DCU105 processor to go along side my AVX5000 head unit. Now after the install I noticed that I am not getting any sound when I play the radio or mp3 cd's. I do however get sound with DVD and cd's.

Wires I have / have not connected to the HU
B+ (Yellow) - Connected
Ground (Black)- Connected
E-LAN terminal - Connected
Line-out terminal (Front, rear and sub) - Connected
Digital input terminal - Connected

DVD MUTE wire (Pink) - Not connected
NAVI MUTE wire (Brown) - Not connected
Front and Rear speaker output leads - Not connected as using amps
VTR input terminals CH1 & 2 - Not used therefore not connected
VTR output terminals (CH1 & 2) - Not used therefore not connected
Video input terminal - Not used therefore not connected
NAVI-VOICE input terminal - Not used therefore not connected
Video output terminal - Not used therefore not connected
RCA digital input terminal (DIGITAL 1 ) - Not used therefore not connected
Optical digital input terminal (DIGITAL 2 ) - Not used therefore not connected

I know I am getting reception to the radio as the 'ST' display text for when a station is selected is on and not flashing as it would if it had bad or no reception.
I have been speaking to a few people and someone suggested that it could be to do with a digital bitstream signal, that DVD's and CD's can pick up via the digital input lead but the radio and MP3's are not in a digital format therefore not being heard.

anyone got any ideas???

Cheers
Adam
