I have an A8 with MMI, so no radio head unit and no cassette deck to feed my IPOD into. The Griffin Itrip is practically useless as you cannot lock on to a radio station to get a good enough signal for it to work. I got tired of waiting for Dension to launch their Gateway 500 ( £ 300) super dooper... fibre optic MMI interface for IPOD, So I bought a £ 20 cable that wires into the TV/TUNER in the boot of my A8. I was a bit sceptical but it works perfectly well and sounds great. If anyone needs some advise , pictures , contacts etc let me know.
