My car came with the 6FL USB/Aux option in the armrest but I wanted to get the iPhone mounted on the dash so I could easily dock it, view music artwork, and navigate with Navigon. I bought the CableJive Car Charge Extension Kit
and the ProClip center mount
and got started. Note the ProClip mounts for BMW need to be specified with or without factory Nav and with or without wood trim. You can also choose between the Center Mount, Angled Mount, and Left Mount. I chose the Center Mount and my part number ( 853739 ) is without factory Nav and with wood trim.
Not pictured are the DockStubz and 12V micro USB charger that come with the kit. The connectivity in the end will be Aux/USB socket to the OEM BMW Y cable to the DockStubz adapter to the 6 foot dockExtender cable to the ProClip mount with dock pass thru. The 12V adapter plugs into the DockStubz unit.
I measured and cut slots in the ProClip mount to secure the cable.
Bottom side view of the clip mounted with the cable attached to the dock. Here you can see the slot is just deep enough to provide clearance for the cable when clipped on.
Top view show the cable through the slot. This slot has a tapered edge to accommodate the angle of the dash trim.
Head unit removed to route the cabling behind and into the center console / armrest.
Cable routing through the shifter area. I also went with a short shifter here.

Close up showing the relocated USB/Aux socket. You can also make out the body the of BMW OEM Y cable. The 30 pin dock connector is attached to the DockStubz (hidden) and then the Dock Extender cable which you can see running toward the left. Hidden from view is the 12V to micro USB adapter which plugs into the DockStubz. The 12V adapter is way too large to plug in to the 12V socket and would also caused exposed cables so I modified the housing, cutting off the socket end and soldering the connections to the 12V wiring underneath the console. There is enough room to push all the wiring inside the console for a completely hidden solution. Note the second USB / Aux socket shown in the armrest in the previous picture is currently not functional, it is just covering the slot. It may be possible to put in a USB hub and cable to maintain the possibility of using a USB drive.

You may wonder why I purchased a second USB/Aux socket (84109237653). Along the way I discovered my USB/Aux socket in the armrest was flakey as it would drop the iPod connection and revert to Aux and USB. Charging had worked when I was using the short BMW Y cable in the armrest but with the CableJive dock extender it would no longer charge reliably. Zack from CableJive provided instructions for how to properly use the setup. Bottom line is I just have to start my car first and THEN dock my iPhone and everything works great!
