Unfortunately, only half an improvement in contrast to the JVC RV-NB 90 BoomBlaster

I had previously never quite satisfied, any Macke, there has been always. So also here:
Unlike the JVC RV-NB 90 BoomBlaster the problem has now been solved with Bluetooth and works flawlessly!
But the poor radio reception in FM (slightly weaker than at 70) and the practically nonexistent DAB reception is unfortunately still. In addition, the USB flash drive display is called only for directories, so albums, not even for songs or files that are displayed numerically. Unfortunately, so only half improvement. Therefore, the unit went back again.
Supplement: The JVC RV-NB 85 has a comparable FM module as the 70s and is in the FM reception slightly better signal strength, while here the worse of the module 90 was built in 100. In addition, the 85 has a Namnesanzeige the USB stick for directory and file.

Therefore my advice: buy the 85. I've also made it so. So far the best device from JVC, with respect to functionality and entire functions and not just half.
