i currently have an iphone 4s and use the kensington liquidaux deluxe kit with no problems. heres a sample picture of it: it charges my iphone 4s, plays audio through the dock (not through the headphone jack) and plugs into 3.5mm line in on my car stereo. it also has a wireless remote that attaches to my steering wheel so i can play/pause/skip/shuffle effortlessly. basically the perfect solution for me and the 4s and it cost me about $40 at the time of purchase. now i'm thinking of upgrading to iphone 5. obviously the dock won't work anymore (i've also read the dock adapter doesn't work with the kensington liquidaux for whatever reason) so i'm looking for something pretty similar to the above. any suggestions would be great.
