Ok! First of all you have to install the newest software downloaded from B&O Official site.
Secondly, and after you have installed the software (remember not to connect the PC2/Beoport to USB prior to the installation because it is a problem) you can make the configuration of Beoport where you can add the radio function of the BC2300.
Note that it will not be possible to listen to your n.music from the Beoport by pressing the N.Music button or anything else. You can do it the other way around.
Umfortunately some B&O product are not upgradeable thus you have to find a fair solution to either upgrade to a newer BS or use it separately.
