Tucson Premium Model 2015 RDS radio receives – NO INFO –

Hello all, I have an RDS radio in my Tucson Preminum instead of a DAB+Radio Normally the recorded information on an RDS radio from information like song name, performer, important events and warning messages that run as a flow test over the screen. Unfortunately, this is not always the case with my Tucson. Transmitters like RPR and FFH do not make any information appear on the screen. It just doesn’t come in. I have to say that these transmitters are in close range and from In my old cars, an info came in here. However, the radio in the display brings information from stations like SWR3 and HR3. Strange!!! With these stations, however, only after a certain time of operation an info comes in. Has any of you had similar experiences? My dealer thinks that this would be normal. He even showed it to me on similar models. With the sender-strong transmitters like FFH and RPR only NO INFO comes there. If RD So S wouldn’t be good enough for a normal radio.
