The player is easy to use and the most important functions can be accessed directly from the control panel, partly multiple key assignment. The included remote control contains all functions as a separate button. But this I use hardly. The transmission to the radio is good and is rarely disturbed (I use 87.5). Can you turn off the unit, but that does not bother me. Get out of countries and socket in the glove compartment, that's it. If I use the device again, then will continue to play the last song. Are the only supports up to 4GB SDs I find a bit thin because today should be in there already more. Otherwise, the transmitter is but a recommendable device!
