2) I had no problems with my reverse camera not coming on until I got the latest firmware when I brought it in a week ago. The fix was for a brake-release bump so it's not related, but it seems the latest firmware causes my camera not to come on at random times while the PDC works. It has happened twice already. No other errors such as the DSC.
