What's the tidiest Iphone 4 integration in an E53 X5

[Kev]

Hi guys,
Avoiding the intravee/dice solutions, Im looking for a cradle that sits under the armrest, takes and Iphone 4, charges it, and connects to the AUX input.

Basically to replace the 3.5mm Jack + Charge via cigarette lighter + cradle solution that I have now.

Do you know if BMW actually make an Iphone 4 cradle for the E53? If I need to make the connections manually thats ok. Of course using the headphone jack wont work with the cradle solution so i'd need a line-in solution from the lower connector if possible.

I'd also like to have a BT pair button in the armrest for my retrofit BT installation.

Has anyone a similar need, or found a solution out there?

Cheers, Kev
