It just depends on what you need/want. The regular lockpick enables navigation tweaks/video in motion as well as having a rear view camera input, and turning on the rear view camera at any time.
The CHR550 adds to the lockpick with an ipod cable that allows you to control your ipod via the steering wheel controls. It does not allow control via the touchscreen. It also has inputs for additional cameras (front, rear, left and right sides). You can also show videos from apps that support the ipod video out like you tube etc. The gui on the CHR550 is not the cleanest and the steering wheel control works but is not to brag about.
Bottom line, if you just need video in motion and the navigation restrictions bypassed, the mygig does the trick. If you want additional bells and whistles, the CHR550 is what you need.
