siemans rd3 (01) upgrading?

[quintet]

I've been meaning to update this thread for a little while, the Yatour device is working ok although the sound quality does drop when it's used. One of the things i always really wanted was bluetooth, i purchased the item pictured in early 2024 & although bluetooth connection is obviously required i found this device much more to my satisfaction as it meant the aux connection between the Yatour device & my phone is no longer required. One bonus is that the Yatour device has a usb port which means it can charge the bluetooth device.
