Just a setting that is not noted on the website or the then very small: it works with miniSD cards. Used in my car (renault terminal plug and play), it works fine. No startup latency (except when first loaded). Its dimensions allow the closing of the terminal cover, the key is not visible it possible to leave it in the car without attracting envy. I have a second 32GB card that works just as well. We arrive by against in the last phase of miniaturization, smaller would be too complicated to handle. Ditto for microSD cards, if they are easy to change, hard to find their place without losing them.
