Can you put in your own POIs that will show up on the map as you are driving with the OEM Navi system? I wanted to put all the speed camera locations for my area in there, but I don't think the Navi. allows something like that.

 

Since the data is housed on a DVD, there is no place to store any additional user data. A memory stick slot would be nice

 

nope, not possible on the 3G navi. Also the memory slot we have is for factory use and data logging use for diagnostics.
