Now I can say it. The DICE unit is one giant piece of shit. Having been down that road, I don't know how they continue making such horrible products. As far as longevity and integration are concerned, I loved my Intravee 2 setup. If you wanted to do that, you would have to procure an Alpine KCA-420i iPod controller (Ebay is a great place) and an Intravee unit. The Intravee is made in the United Kingdom. I had to have it shipped across the pond.
I haven't had one single issue with my unit. Superb browsing and control of the ipod from the unit (it locks the ipod controls), reliable and relatively easy to use.The only down side is that it doesn't charge your device without purchasing an adapter.. Haven't investigate this.
I bought a used 4th generation ipod nano, threw a fair amount of music on it and leave it in my trunk. Been in there for 3 days and still haven't had to recharge it...
Others with alternative iPod connectivity solutions please chime in to help our brother out...
