I bought this product to connect my Samsung Galaxy Note 2 to my E Class 3.5m audio jack and USB in car charger. My previous phone was an iphone 4 and there are hundreds of devices available that will do this, so (wrongly) assumed there would be plenty for my lovely new Note 2.
Alas, on receipt, this cable did not work, either to charge the phone or route the audio. I suspect that the metal USB connector isn't long enough to make a proper connection when plugged into the Samsung, though I cant be sure of this. The lead is also MICRO USB not mini as in the description - so I wasted a couple of quid on buying an unnecessary adaptor.
The seller needs to check this product actually works on a Samsung phone before selling it, and should describe it accurately. I've contacted them and will amend the review if the cable I was sent turns out to be faulty, but in the meantime I would advise you not to buy it.
UPDATE: The seller has amended the description but the replacement cable sent also does not work. I've noticed that the USB symbols printed on the side facing DOWN whereas every working peripheral for my Samsung and iPhone has had this placed facing UP. The cable fits - but sadly, it's useless.
Returned for refund.
