I have a Kufatec IMA with the Alpine 425i set here. These are the components that enable you to integrate an iPod with your rns-e - and it is the most complete integration out there. You can control the iPod with the rns-e controls, and see the album art on the screen. All cables are included and the system works perfectly.
I am also selling my rns-e (listed in another ad)
My prices are:
RNS-E: $649 plus ship
Kufatec IMA with Alpine 425i: $329 plus ship
Package deal: $949 plus ship
Please shoot me an email or a pm if you have any questions.
