I have the Lockpick CHR550, I love it! Unlocks everything, video in motion, typing in directions for nav while in motion, etc. The CHR550 also has hookups for I believe 4 separate cameras, two auxiliary devices and comes complete with an ipod hookup. When plugged in you have full control of your ipod from the steering wheel controls and songs and playlists shows up on the headunit.
Another neat feature is the auto camera function, you can set it up to have two turn signal cameras display automatically when you turn on your turn signal. Theirs also an option for auto front camera for when your going underneath 8mph. Also the auto rear camera too. You can also set it up to have one camera on all the time. For those that have stock backup camera I found out theirs power going to it all the time not only in just reverse so I set it up to display on my HU all the time. Until I install a front camera that is
Many people report problems with lockpick quality and seem to have audio problems, I believe this has been stamped out in there latest models. I haven't had a single problem with mine.
