Just completed install of the Iron Cross HDPDPLUS2 iPod integration kit. This unit was easy to install on my 2011 Flhtk took about 30 minutes. The hand controls are great to have when driving but I plan to change my playlists just for the iPod when I use the bike because my current iPod has about 15000 songs. I love the fact it is plug and play with no software upgrade like the HD system. Other great feature is now my Aux plug is avail for my zumo 665 again to have it plugged in all the time.
Before buying the iron cross system I was plugging/unplugging the aux plug depending on my music mood from iPod vs xm so this is smooth and easy. I did not mount the iPod in the trunk bag tho...because you can over ride the iPod by pushing "locked" on the radio and manually over riding the radio head to use your fingers to control the iPod.
I suggest saving the money and going with the Iron cross system for ease of install, plug and play, and super fast shipping. Did I say I ordered at 11am Monday and I got it in my mail the next day at 1pm.. Granted it only went from NJ to CT but it was shipped next day for free by them.
Btw my iPod is mounted on the fairing right side top using a pro-fit international LB600T -LoBoy motorcycle mount and a profit international MI-100BT custom holder for iPod classic. I did have to trim the opening for the cord about 1/4 inch to get it to fit. All pro fit international items found on amazon for much cheaper than the ProFit international site.
Last note I initially tried to use a "Y" stereo plug to plug in iPod and zumo GPS into the Aux plug but the audio quality was terrible and barely audible. With all the frustration I decided to just spend the money and happy so far.
