I wanted to share some information that I had a very hard time finding. I recently purchased a 2019 Malibu wakesetter 22 MXZ and I wanted to be able to use the GPS. You still have to purchase a GPS antenna. Amazon is a great place for this and the Navionics sd card for your region. On the 2019 Malibu's, where you plug in the SD card and antenna is in a new location. It is not on the back of 7" display down on the side. I found this out the hard way. The new location is behind the dash on the drivers side. To access it you will need to pull up the cushion in the very front of the boat where there is a storage box. Remove the 4 screws. You can access the subwoofer from here as well. Above where the subwoofer is you will see a black control panel. You screw your antenna in to that and also you can pull the square rubber piece off to find the access to the sd card slot. Pretty simple to do but not a lot of info on it yet being that it is so new. Hope this helps anyone who is wanting to view the lake maps on their boat.
