I brought the RDS one. I have not yet installed it but you have to tune the radio to read the info. But then you have no music till you turn to your favourite station. But it doe come with a red LED that flashes once the temp starts to get low. So then if you want to know just how cold it is the you have to press the preselected button to get the info. I was going to get the one pictured in the preface lift photo but in the face lift model there is just nowhere to mount it neatly.
