hi, first post, I have a black RS4 (optic pack) due end july, after going through all the usual ICE options (very confusing) i settled with sat nav + 6 cd autochanger as the salesman didn,t know enogh about the i-pod interface, i saw in a previous post about a Dension Gateway 400 is this easy to fit, and will you be able to see song titles on satnav display and be able to pick and choose songs like on i-pod or just skip to next. many thanks, hope it makes sense
