I just recently bought the Avic-X710bt and installed it in my Vehicle, now I'm trying to update the system but it will not update, I'm doing everything the install update instruction says but it will just not update it, I've already made sure that the system that it has is not the one up to date!!! help please how do i get it to update? when updating it will let me know it's updating right?

What version is on the system?

The system's is 3.020100 and the map's is 02.000500 which my understanding I just need the map's update

There is no map update. The latest firmware version is 3.02 but it is insignificant. Don't worry about it.
