I just installed the MyGig Lockpick v4 on my JK, which in addition to unlocking all the MyGig functionality that's normally locked while driving, it also allows up to three cameras. I bought two of their waterproof night-vision license plate mount cameras and installed them front and rear. Sweet setup, but a bit pricey.
MYGIG LOCKPICKDid you purchase it online? If so, what is the link?
