Minimaxx problems

[tomcat955]

Hey I have a old minimaxx I got from a friend I am trying to make work, it is set up for a dodge I am trying to tune my 2013 f550. When I plug it in it is stuck initializing vehicle i have tried plugging it in slowly I have tried buying a sd card files and putting them on a sd card and formatting it to fat. Does anyone have the updater? Id really like to try to fix this if possible.

power it up with a computer cable. then go to to menu>change vehicle and select the model you are trying to tune. Not all MMs work on 13-14 trucks.
