When ever I turn on my GT-11 it read, 'bad formate'. I can't formate the card either. When I do it reads 'FAIL' followed by '-32768.aah' and then 'S6892480'. Does anyone know what that means and whether it's time to retire the GT-11 and get a GT-31?
Thanx in advance

Yeah my GT-11 plays up too. The card reading/writing is unreliable. I'm getting around it using the onboard data logger. Have you tried it?

I'm tossing up whether to buy a new Navi or not. Most probably I'll keep using the one I have till it completely dies.

Have you tried another card?
and/or have you tried formating the card on another device?

Thanx guys. Yep tried formatting the card on other devices and tried other cards too. No good. DavMen, I'll have a crack at recording on the onboard data log. Cheers

Is there any sign of corrosion on the screws inside the cover? If so you've probably had a bit of water inside, I've seen a few GT11's that died look like that.

Yep there is & I suspected this might be a problem. Wasn't sure if it was software thing or hardware. Hardware it is then Oh well time for an upgrade
Thanks for the insight Mr Decrepit

Try the onboard data logging and see how that goes. The card reading/writing has been shot on my GT-11 for about 9 months but it still works reliably with the data logger. When I get home I write the data to the card as that works and then upload the data to the computer. Once on the computer I then wipe the onboard memory.

My rationale is all this stuff is getting cheaper and there may be a great waterproof GPS around the corner.

I had this happen as well.

I'm pretty sure it's because the gold plated contacts that touch the card lose their springiness after a while, and so don't make good contact with the card. I tried bending them down which sort of worked for a bit, but in the end the damage was terminal (pun intended )

No idea how to fix it permanently though, apart from not sailing in chop...

OK Mobydisc thanx for that. Yep data log is still recording, i think. I can read the distance and my 2 sec peak etc, but how do i get it onto a card to upload data to a computer? Can't do that as it won't save to a card, even I go to 'save to card' command in data logger?

Ads72, you can download direct to the Navi program, by hooking your GT-11 direct to desktop. If you still have the data with the GT-11 it will explain in that, on how to download. If not go to the website and its all there step by step.
Hope this helps.

I modded my card by building a bulge of alredite on the car on the other sides to the contacts. I did this in the rationale to get the contacts to connect to the pins. It works but for who know how long?

Yes you can use the navi application to read the data too but I think thats Windows only.

Thanx Mineral1 & Moby. Yes that's right Moby, PC only. I'm on a Mac
Anyone know of a program for Mac OS 10.6.6, that i can tether the GT-11 to and down load the data from, love to hear from you?

I use Parallels Desktop which then runs Windows.

Works a treat, lets me download to my MacBook no problems

Cool Thanx Nebbian, that's what i'll have to do then. Parallels it is Cheers

For the price (~$5) of a jewellers screwdriver and a trip to a junk shop/most supermarkets, you can rescue a drowned GPS if you catch it early enough. Also its good for resetting one thats frozen on a good day right when you want it most. Its handy to have to help out guys on the beach who dont have one.

Pull the case open and disconnect the battery lead.

If the GPS was frozen (and not drowned), wait about 5-10 seconds before reconnecting the power cable. Should be good to go again.

In the case of a drowned GPS: Disconnecting the battery significantly reduces the corrosion rate. The slower you get to the battery, the greater the damage. Rinse the top circuit board in fresh (preferably distilled) water or isopropyl alcohol (better) to displace the salt water. If the unit is already corroded from a prior event, you can gently scrub with a toothbrush to remove the loose debris. Let it dry out for a couple of days if you used water. Should be good to go within the hour if you used isopropyl. It takes a while to dry out underneath the GPS chip and the LCD.

If you spray contact cleaner into the unit it can help with corroded SD card reader terminals, but you risk getting it into the LCD. Some contact cleaners eat plastic so beware, it might wreck the display. wetndry can be used to polish the terminals but this usually wrecks the plating and it will corrode more readily.
