Today I splurged on a new car stereo. Again. My 'old' thing was truly horrible, so now I bought a real brand. Pity that there seem to be no car stereos that take SD cards anymore. So I bought one with a USB connection instead:
It fits very nicely with the dashboard of my car, was easy to install, and it works fine, as far as I could see in the 5 minutes I tried it.
