Retrosound devices – does that dive what?

Hello community! I took a break for a few years and I think that I should change from cassette after all. I have a Opel Commodore Coupé for 17 years, which I had at that time equipped with a stereo system. Since I wanted to leave the Becker Europa (still functioning via center speakers) in the dashboard for optical reasons, I have accommodated radio, active switches and changers in the glove compartment. Unfortunately, I have found that the radio now has the Since the Becker Mexico Retro is really too expensive for me (you’re getting more reasonable in old age), I Googled a bit and landed relatively quickly at Retrosound. Visually, it would be an adequate replacement for the original. But how does it sound? What does “USB on the backside”? I would be grateful about reports.
