Eos_Up,
You may want to just use the aux-in for the iPod. You can always get a mount and a long cable and manage the songs on your iPod through the iPod itself.
I have had 2 different solutions. In my Passat, I bought a unit that plugged into the unused CD changer giving both audio and power to the iPod. It did not have control through the radio. I got a mounting unit to hold the iPod and snaked the cabling from the glove box to the mount and controlled playback in the iPod itself. This can be done using the aux-in without giving power to the iPod.
In my Eos, I got the iPod adaptor. It powers the iPod and I can have some control through the radio, but not optimal control. The adaptor mimics a CD changer and will give you access to the first 5 playlists on your iPod. CD 6 is used for your entire library. You can skip songs and use the radio's control to 'shuffle' by changing the settings to mix.
The songs are not displayed on the radio and you cannot navigate through artists, genres, songs, etc. You are limited to the first 5 playlists.
If charging the iPod while driving is important to you, get the iPod kit. If managing your music while driving is more important to you, use the aux-in jack.
I hope this helps you make your decision.
