Eagle Cuda 250 FF help?

[kaya_one]

Looking for anyone who has owned and operated a Eagle Cuda 250 fishfinder. The center button (with the up-down-left-right options) stopped working. Too bad because the whole ff is shot if this button doesn't function.
Anyone have this issue?
How do I fix it?

I bought this ff with the kayak over summer and it must be at least 4 years old. Any idea if Eagle is willing to fix if I pay?

There are 4 or 6 star-head screws on the back side. If I get it open any idea if I can fix it?

Any help is much appreciated. I am just trying to get rolling and up to speed since I am a newbie and don't want to get set back by having to buy another ff.
