Changing 2004 BMW Z4 Business Radio

[Hcortes1]

Hi!
I changed my 2004 BMW Z4 Business Radio but I have no radio sound or in dash cd player.
I can hear the Console 6 Disks player tough
Could it be a programming issue or an amplifier one?
This was the reason for me to change the radio unit to begin with!
Thanks
Hernan

Is your amp sitting in water? Usually that’s the cause of no sound in a higher spec system
