RCD300 ADD IPOD CONNECTOR ?

[Digger3]

I have a rcd300 + armrest cd-changer, I want to add a ipod/iphone connector,my question is whats the best way to just add one off the oem ones
that goes in the glove-box (1KO 051 444).
or remove the changer and plugg into that connection, would the later give better sound and if so what do
I need is it just plugg n play, can they both be control'd by the head-unit will it show track/music info ...

I know theres a fare few questions there  any advice much appreciated...Thanks

The downside of this adapter is that it only allows you to play 6 playlists with upto 99 tracks in each playlist, you can't pick an individual track, and you don't get any track info on the display
