The only thing I noticed is a little disturbing, the display reflects sunlight through the sunroof.
Preset buttons I do not miss, because for me the operating concept is conclusive (the successor has 48 preset buttons, but a worse display).
5 stars for function sound (massive adjustment, transition frequencies, duration, etc.), BT FSE, DAB + / FM reception, sound and frequency changes, BT Streaming, etc.
I am completely satisfied for the price and highly recommend the Kenwood KDC-BT73DAb further, who absolutely needed preset buttons, to buy the successor model.
