Hello people Is there someone here in the forum who owns a vehicle with the configuration Premium Sound + SUB? The models V70, XC70 and XC60 2012-2017 with Sensus are meant. (with the V60, S60 and S80 this configuration did not exist) I would like to retrofit a Volvo amplifier with SUB (have bought the parts again). My problem is that Volvo cannot play the necessary software on the amplifier because my vehicle is not supported. This is only possible with vehicles that have been delivered ex factory with Premium Sound. There it is easy to start the “AUD reload”. If someone wants to support me in such an action please report me. Of course, there is also a fee compensation. Thanks now!
