Dragonfly 4 Pro w/ update 12.09 not working properly

I have had my Dragonfly 4 Pro since November of last year. No issues at all with it. I did the update to v. 12.09 and then my problems started.

Depth only works around 10mph and below, if I go above that, the screen goes blue and shows 1200'. Sonar does the same thing, works till about 10mph and then goes white.

GPS seems to take alot longer to get my position now.

I did a reset on the unit when the issues first started to see if it would fix it, and it has not.

Thanks,

Stephen Phillips
