Furuno marketed the BBWX1 and now the BBWX2 as a Sirius weather receiver. The Vx2 (when the BBWX1 released) has no way to even control audio features. The unit made for Furuno just happens to also have the ability to accept Sirius audio but it wasn’t marketed or sold as an audio unit. At the request of customers, a small audio control was added to the software on the NN3D which will control audio on the BBWX1 and BBWX2. There hasn't been any recent discussion that I am aware of to improve the existing audio control for the NN3D. The weather was and still is the focus of these units. In fact for the longest time Sirius would refuse to activate the audio on the BBWX1 and BBWX2 because they were only approved for weather. After XM and Sirius merged, they at some point decided it was okay to allow audio to be activated on these units. I will pass your suggestion to product development and we can cross our fingers.
