dragonfly 7 first generation - looking for last software update

Chuck,

I have a Dragonfly 7 first generation and I am looking for last software update.

My Dragonfly 7 does not have a wifi so I am afraid when I updated my software to upgrade 7 I may be [censored] up my Dragonfly sonar.

Please HELP! thanks
