fwiw, the Silabs app isn't showing RDBS text either.
update... the chip in this device is marked "Silabs F321 ECNA15 06124". I can't find that on the Silabs site. Still looking.
update... the F321 is an MCU, so that's the USB handler and general brains. Still looking.
The first stop for the antenna signal is a chip marked 4700A09. I can't find a reference. There aren't any house markings on it so I can't ID a manufacturer. My guess is now that the FM receiver itself is NOT Silabs, but the MCU is loaded up with code to emulate the Silabs protocol. I'll keep trying to ID this chip.
