I actually don’t have a backup camera yet, but it was another benefit of getting this head unit. I haven’t even begun to research them. I “might” just go with the style you mount over the license plate but then again that might erk me too much. Low light sensitivity is going to be the key for me. I don’t really have any issues backing up the X except at night, particularly in low light levels.
