Dear owners of the Sony Walkman “NW-A828/A829”, “NW-S615F/S616F” and “NW-S715F/S716F/S718F” – there is a firmware update out there for you. It’s a minor update, but apparently fixes volume issues when using those Walkman devices with the CMT-V3, CPF-NW001, SRS-NWGU50, SRS-NWGM30, SRS-NWZ10 stereos, and WLA-NWB1 Bluetooth adapter. However, the only catch is that its being offered by Sony Japan and I’m not really sure if it will work on your model if you live outside of that country. Hopefully someone can figure it out.
