I purchased one of these about a year ago, but took a few months before I installed it. After installation I was met with a barely functioning device. The display on the radio for control of the iPod doesn't work. And it sometimes causes my radio to stop showing XM data at all. And my iPhone states that the device it was just plugged into is not a proper device and the control may not work. I've read a lot of good reviews, but I think those were previous devices. It appears Scosche has changed them and the new models really stink. Also, these do NOT recharge your iPhone or iPod. Look elsewhere for a better device for this purpose.
