Been using this in my care all winter. It is fantastic. I just wired it to an old cigarette lighter adapter end. So in summer I will just plug into to aux input on back of headunit.
I strongly recommend.
Has all latest codec etc I frankly noticed no degradation in sound. I tried 2 cheap ones, that did not work well.
I may have to get another one so I have one in boat and one in car as I have enjoyed it so much over the winter.
