Just curious if you managed to get this working with an aftermarket DAB unit? I've had the same issue with our 2011 XC60. AM/FM etc. works but a scan of the car shows the following codes:
DABM U300004 Control Module General Fault information, system internal failures.
Did you manage to get the dealer to turn off MOST? Does it need to be a main dealer or could an independent specialist do it if they have VIDA?
Thanks
