DAB+ / fm commit fails with HR after transmitter conversion

Hello, in my V90 MJ2020 early the sensus audio system is installed. At the DAB+reception of hr3 the system switched to the underground car park (no DAB+ reception, but VHF goes) always reliably on fm. When leaving then back to DAB+, unfortunately because of the not completely synchronous signals (or because of a different signal processing in the device) always with a slight time offset. Since the Hessian radio has regionalized its DAB+ transmitters a few weeks ago permanently , there was hr3 as superordinate, nationwide station no longer to be found at first. In the DAB+ channel list I then had to record the new station hr3 middle-hessen in the favorites. So far, so good, but… … now the switching to fm does not work anymore. When I drive into the underground garage, I see only a helpless rotating ringel with the text message ‘no reception’. A switch to fm happens e.g. at ffh still without problems, but with the stations of the hr no longer . Why? Can this be due to any settings in my system? The DAB/DAB and DAB/fm handover are both enabled in the options. I had already contact with the hr, which explained to me that some radios do not conform to the standard the alternative FM frequencies sent in the DAB+ data stream ignore and e.g. search for the same station name of the RDS information. If this is also done sensus and instead of the alternative frequencies now searches for hr3 means, the fm-Prog But only hr3 means, then of course nothing can be found. Is that just the case with me? Who still has the same problems with the regionalized hr or other channels? Are there any suggestions for solutions? Thank you for your help André
