Questions about Sony Cmt-X5cdb

In our house, DAB reception is already not optimal. We have an antenna near the windows and in a rural area (Thurgau). I would not recommend this device for mountainous areas.

The unit is absolutely unusable, I have the same experience. The device is now only in operation with me thanks to the USB connection, so I can listen to music recorded on a stick. I would also be interested to know if anyone knows anything about an alternative antenna.

According to the manual, it is intended as an output device when paired with Bluetooth, aka for a mobile phone, etc.

That would be a good thing, but I haven't tried it yet... but you can probably only connect external devices as music sources via Bluetooth. Otherwise, you can check the operating instructions. https://www.sony.de/electronics/support/res/manuals/4528/45283044M.pdf
