Here are two reader submitted iPod nano docks. [ian] found this guide for mounting the nano in a truck. The headunit already has a line in so Kevin just chopped up the nano’s retail packaging to make a nice holder.
I didn’t realize this, but the dock adapter that comes with the iPod doesn’t work with current products or at least not the mini dock. [Caius Durling] trimmed up his adapter a bit and installed it in his mini dock.
