Please let me know if you get anything working with the extender. Meanwhile, I have sent another email to BSW asking what type of signal is output by an iPod and what they use in their DICE systems to get that signal from the dash (where the iPod is) back to the trunk (where the CD changer port is). Seems like if there is a conversion at any point in the DICE chain to S/PDIF or I2S, then the digital output card from Eutronix would be able to do the same thing. I'll let you know what he says.
