ah welcome to my world. found this out 6 years ago and wont go back to apple in a hurry - the most frustrating feature of apple - the stupid warning advising you you are not using an apple cable - who cares and did apple make cables for cars then, no they didn't then but my alpine was ipod and iphone compatible - my iphone 3g didn't work because it wasn't an older iphone model - wtf
apple didn't want to know as it was outside their complimentary 90 day support (is that nice of them, spew). I went to an apple shop and I told the sales guy about the problem. his solution was to buy a non existent apple made cable.
so I bought a newer more expensive alpine stereo that was iphone 3g compatible and it worked, sort of, as the sound would cut out nicely without warning whenever it felt like it and with the stupid message.
I wont go back to apple and their stupid archaic closed door operating system and overpriced accessories and phone. made me laugh when apple said it cost $200 to make an iphone.....hahahahaha. if it cost $20 id believe them
I then bought a £10 sandisk sansa player that had no problems and still ok after 6 years, plus sound quality is far better than the terrible iphone.I sold the iphone and bought a Samsung s2 instead
