Quark -- no it is not the brightness wheel to the left of steering. As soon as I remove my LockPick the picture quality returns to "normal". Can you test something for me, that I just noticed today? If I use my navigation system and enter a location, then hit go and start driving, the vehicle speed in the lower right corner of the 8.4" screen, when Nav is selected, always says a speed of 0. My speedometer and the speed in the EVIC (small digital screen in to the left of the speedometer) displays the correct speed, however, the 8.4" Nav screen always says 0. I, again removed the LockPick today and the speed displayed fine on the 8.4" screen. Only with the LockPick do I always have a speed of 0. By the way, I have a 2011 R/T in Canada. Are you in Canada?
Also, have you added a front camera? I just did this today, using the CoastalEtech Bar cam and the quality is also poor for that. Very washed out. It is almost like a white/grey camera, no colour. However, I also have an iPod hooked up to the LockPick and the quality of the video from that is perfect. So, reverse and front camera have poor quality, but iPod has perfect quality. I can't figure it out. It is almost as if I need different contrast setting for each camera that is hooked up to the LockPick.
Finally, one more question for anyone who hooked up a front camera. Now that I hooked up the front camera, my auxiliary outlets that have the "key" on them (ie. only work when the car was on...found by the very back lift gate, and just below the 8.4" screen in the cubby area) no longer work. The outlet with the battery at the back of the centre console, in the second row of seats, works fine.
