DAB+ option code, remediation not possible

Evening together, need your help. I had an appointment today with my friendly to let the DAB+ module rest for my V70 model 2016. The preparation was available with me, I had already checked this 1 year ago in the old My Volvo portal. That was still going on… Also in the trunk looked, the fiber optic bridge and the connection cables are under the back seat or the panel. I thought everything was no problem, the warehouseman had the module before half a year ago. r has also been looking out to determine the price, as far as ok. Today the friendly called me, he can not rest the module, because the option code does not fit. He talked about there are 3 pieces according to Volvo, that are 935, 934 and 832. My vehicle somehow had 822, he said. Finally he said that he can not make the recovery so. He leans on the document from Volvo Accessories DAB/DAB+ Didgitalradio option 39327. Can someone from euc h explain the code thing, or is it another story of Volvo where the “special knowledge” has to be applied. Can’t honestly believe that there is no module for my vehicle despite the preparation. I had to explain the RTTI function to him at the time and put an order number on the table. Maybe there is some advice and can I (and the owner) provide information?? Thank you and the beautiful evening still… PS:In the SuFu I found nothing specific. en
