This is my first bird. I own 2 brand X. It would be nice to have the ability to load only the files you desire to use from the SD card into the Humminbird unit. Brand X allows me to load only the files I will be using in a one day fishing trip. Just saying. So far I love my 998. This option would allow for more convenient management of waypoints and such. Maybe I missed something but I have to download everything on my unit to get to the waypoints I want to work with.
