After battery replacement car wont start

What is your question?

I have a 2009 Honda CRV which required a new battery. After the battery replacement, the car still wouldn't start at all (battery was brand new). The only way I could get it to start is by unplugging the plug that's located inside the car on top of the rearview mirror. I think its the security system. When unplugged, it allows the car to start and i'm able to drive, but the back facing camera, radio & navigation system do not function, nor does the automatic starter/remote.

How long has your 2009 Honda CR-V had this problem?

Since beginning of February
