2004 XC70 radio and electronics

Does anyone know if the 2004 model XC70 radio is integrated into the
vehicle's electronics? We were considering a purchase of an XC70
with the intent of replacing the factory head unit with an aftermarket
stereo, but the installer believes that removing the factory radio
will actually disable the electrical system. Obviously, this would
be bad.

We have a call in to Volvo through the dealer, but I figured I'd ask
here, given the technical expertise and experience of many of the
regulars here. If you've got answers, solutions or workarounds, I'l
be very grateful.


Cheers,
