Hi Des,

yeah the GT-31 is the GPS to get. Its not perfect. My old GT-11 which is very similar, finally died due to corrosion a few weeks ago. I'm sticking my GT-31 in a plastic sealed bag inside the pouch.

The Navis have Speed Genie which can display maximum speed as well as a few other speed categories. I like the 10 second speed average as that gives a better idea of what will be coming up on the screen at night.

CYA

OK so I have set up my new GT31 with what I think is the latest software: V1.4(B0803T) but with this I do not have the keylocked function (2 buttons pressed at the same time which I get on the V1.3(B1123) version)
Is keylocked no longer a function?

Hi RSB. Yup that is what I do. On the V1.3 B1123 loaded GT31 that works fine. On the newer one I have now loaded with V1.4 B0803T software holding down the toggle or both buttons just results in the message 'ACQUIRING SIG'

Evets, You have to go into Settings...find Key Lock ...and choose Key Lock.

thanks Mark and Herby. I have now got that working. Funny thing is I was told about 2 years ago to lock you push in both buttons. Bit fiddly but it works.... knowing now that I only need to hold in the toggle button will make it a lot easier!

Unfortunately it also makes it easier to do it inadvertently, such as when leaning against the board when moving your mast base.
I locked mine before I was aware a key lock function existed and was wondering why I was getting no response to any buttons I pressed!

I have a small cut of neoprene glued around the toggle to stop any accidental pressing

I have a small rubber o-ring which does much the same thing. (purchased from a cheap auto spares shop)

click while in max speed, scroll up or down to "clear" click on that.
Then go to max average, click on that,same process.
Won't work while it's scrolling thru the history panes.

Just on the firmware. Anyone know how to reset history max?

Or (assuming GT31 latest firmware) in speed (in the speed menu) depress the toggle button and delete all will clear all your speed genie data.

Got it. Thanks guys
