Retrofitting DAB+ radio for Seat Ibiza 6J FR SC 2.0 TDI, year 2015

Hello everyone,
Does anyone have any ideas on how I could elegantly equip the Seat in question with DAB radio? I'd actually prefer not to have a brightly colored radio (if it can be avoided). It should somehow harmonize.
Retrofitting with DAB (Digital Audio Broadcasting) is not planned for Seat vehicles. I had emailed them.
Currently, I have a standard, factory-installed radio with a CD-MP3 player installed. The part number is 6J0035156. Unfortunately, I also don't have Bluetooth or navigation.
A 2 DIN unit probably won't fit, due to the buttons located below the radio.
As I said, I hope someone knows something.
Attached is a picture of the radio that is currently installed.
Sure, here's the translation:

"Thank you in advance!"
Best regards,
Jörg

Hello,

I would suggest contacting "usb-nachruesten de" to inquire about their services.

Best regards, Rainer.

Hello Rainer,
Thank you for the tip.
I just emailed them.
I somehow have the feeling that I've contacted them before and received a rejection. I didn't find anything in my emails.
Maybe (hopefully) it was a different company.
I'll know more tomorrow.
Best regards,
Jörg.

Unfortunately, they don't have anything for me in their program :-/.
Too bad.
Best regards, Jörg.
