Please help me out! I purchased a TomTom carkit for iPhone which should be able to hear the music of the iPhone over the audiosystem (RNS2/CD, Touareg 2004). However nor my dealer, nor TomTom or other specialists I consulted knows whicht connectioncable I should need. On the end of the carkit there is a female receptor for a stereojackplug and my former Dension 100 Gateway worked perfectly with a quadconnector to the aux-in of the RNS2, simulating a CD-changer. ???
