To anyone who is thinking on splashing out on getting an ipod kit installed, and in my case already has 6 disc changer and factory fit sat nav, then the best way is to purchace an ITRIP from ebay, various makers, i went for a kensington pico fm unit, that works on fm frequency, u put in a free fm frequency like 94.7mhz, plug this wireless device into the bottom of my ipod nano and bobs your uncle, fannys your aunt, works brilliantly, next to no static noise, same as a cd in quality of sound, ands all for a bargain £30 !!!!!, dam site cheaper then usb plug in kit
Only downside is that particular unit doesnt charge your ipod, but you can buy itrips that do, ive heard these units are trying to be band in various EU countrys, so get one whilst you can!
