And I do use the SD slot, with a dozen GB of MP3. Anything fancier does not make much sense in a car.
I guess my American is showing here, but, do you not want a better stereo in what is arguably one of your most expensive purchases? Your Skoda is just a VW Polo under the skin, and lots of aftermarket headunits are available. I've replaced the headunit in most of my vehicles over the years. Worth it every time, plus it's one of the easier ways to modernize an older vehicle (even my 2008 Toyota Sienna got a new headunit).
