Hey Guyz & Galz,

I have 2 spare GT31's, one works, charges, shows readings of speeds but won't record to card, or save to card. The other GT31 seems dead, won't charge?

Are there any repairers of such things?

You could ask your Captain, if you're not in a hurry. Or you could put your name down for a mini motion, 10X better than a GT31

Yes, that jogs my memory as well I think it was with "navilink" but that maybe hard to come by now. I should have a copy somewhere, but where?

so have you got the download link? I couldn't find any firmware downloads, only documents.

The GT31 wont recognize sd cards bigger than 2g. This might be the issue.

Try reinstalling firmware if possible ?

I'll get hardie's GT31s tomorrow and do some experimenting

Navilink is still available to download via Locosys.
I just did so, still won't connect. (COM PORT error)
If anybody works it out can they give us the word.
I have a young fast guys (record) file, won't load onto card but the file is there in data logger.

Ahh, that jogs my memory as well. It might be the issue of finding the right COM port number. I think I had a trick for that using some other program but I will need to open some jammed files in my memory....... It could take a while!

That's cool, I'm a patient fella

That's possible Richard I'll find out later

Not sure Anita, but I have two here from Joe, with problems, we maybe able to do something with bits from them

Thanks for that Decrep. I reloaded usb driver and navi utility.
It sees the com ports and I can locate the correct port.
Still get the msg 'not in navilink mode or incorrect port'
Tried all ports but same msg.
I guess the next would be to reload the firmware on the GPS unit but I reckon that will wipe the data files?

the toggle switch on my GT 31 has stopped working. everything else is good. Can that be fixed?

I've just managed to get one of Joe's apart, (the micro philips heads are rusted and deep in the casing, I can't get a grip on them).
And replacing the joy stick, is probably beyond my skills. It's very fine soldering required, these old hands are getting a bit too shaky, but somebody more skilled at fine soldering could probably do it.
