Useful guide Roo, good work, but I'm still having Sinker's problem.
It's all working using the on-board memory, realspeed analyses the .gpx files all OK, but when I download the SD card it is a .TXT file and the numbers in that file look a lot different to the .gpx files out of the onboard memory. Realspeed doesn't respond to the .TXT file? What's the trick here?
thanks Ian
Yes it is a text file, and realspead should load it. When you got to
>file >open, make sure you select "all files" then the text files should show up and will load in same as gpx files. you can then save it as a gpx after doing the "delete invalid" thing.
Thanks Decrepit,
I get that far, the .txt file is in realspeed's "open" box but nothing happens when I click on it.
I've since found ,using windows notepad, that the text file out of the SD card looks a bit like the .plt.nmea file out of the on-board memory ( you get 4 different files when you download the onboard memory). That .plt.nmea file works in realspeed. I'll try renaming the .txt as .plt.nmea
cheers
Ian,
Make a copy of the txt file before you edit it as you will need the original file if the guys ask for it to confirm your new world record speed.
The altitude read out on my Navi is strange. Firstly it displays in "f" which I assume is feet. How can I get it to display in metres to AHD? The other thing about it is that it tells me Wello is 200 feet high.(confusing the mountain with the point maybe) And the numbers just keep going up while the unit is still. Does this mean that I will automatically win my gps jumping competition with Jonas Cebalos?

Booted XP and checked Rspeed.
Strange, all the files are in the "file type" box at the bottom, don't have to do anything there. I can double click on my card ".TXT" files and they load fine. Does take a while though, there's quite a delay before it finishes the operation. Are you giving it enough time????
I have renamed the files. added the place name between the existing date and the .TXT. Can't see that making any difference though
Sorry for the delay in answering your question Ian. The files you download from the NAVi via SD card or by cable using NAVilink should open up in Realspeed without any modification. However Realspeed seems to have a few bugs and sometimes the files open, other times they don't. I can't give you a reason why unfortunately. I would try opening them up in GPSAR or GPSRESULTS and see if they work, that way you will know if it's a corrupted file or not. I've had trouble today opening both .gpx files and .txt files in Realspeed. There seems to be a few versions of Realspeed available, you may try a later version to see if the problem occurs.
My young mate did a solo run the other day, turned his Navi on and off, depending if he was sailing or standing arround scratching his bum. He ended up with 4 files, which he copied and pasted into one file. Opened with Realspeed, everything was sweet, got all his data in one go.
This seemed like a great idea to me, stop for tucker etc, without effecting average time or working out best times from each session from that day.
I like the idea, can any wise ones find fault 
No problems doing what he did, the nmea file is basically a text file that can be edited in notepad or any other text editing program. That's the beauty of the nmea system, it is so simple to use. There's no problem leaving it on all day but you end up with lots of useless data that only slows down the analysis programs when they have to load it all in and do calculations.
Thanks for your quick reply Roo.
Also big mobs of thanks for your user guide and input 
A possibly better solution is to leave the unit on all the time, but only log data when your speed is over say 2 knots.
The latest version of RealSpeed and GPSResults both read the GT-11 binary files; these files are an order of magnitude smaller than the NMEA and GPX files, so less reason to turn it off.
Thanks Fellas, between Roo's guide and Tom's how to I'm getting closer.
Have found: Don't assume your new GT11 will have the latest software. The guide from Mt Best shows how to download the latest B0608T version. Try a few times until the GT11 led really starts blinking
Then downloading the latest realspeed version 1.900 got things going.
I learnt not to expect backward compatibility - just stick with the latest
I set the nmea to binary 1 sec - all the other options then become non-selectable. Binary must record the lot, so you don't have to worry about them. Text files are now a thing of the past.
Then if you save the file from realspeed as .gpx you can load them straight to google earth as usual. The tracks show the walk to afternoon tea very accurately, none of those 5.5 knot bursts and zig zag glitches of the Geko.
Hi Ian, any chance you could do the "tin can" walk test that you discussed last year? I'd be interested in getting that datafile.
Hi Mat, that'd be too cruel a trick to play on a new GPS. You'd hope it'd record zero satellites and realspeed would delete the points.
Still getting out at Sandy Point I see. We've had nothing in Canberra, no weather at all - no wind, no rain and no temperature.
Be careful using the latest firmware, as the "T" at the end of the name indicates it is a trial version that is not fully tested. I have already had problems with it switching off in binary recording mode. Also the problem with SD card formatting still exists, I suggest if you are going to use an SD card to get a SanDisk...I have had no problems using them to record nmea data. I now wear 2 NAVis as I dont trust the new firmware yet, this way I have one set to nmea and one on bin just in case they bug out on me again.

As there are still known bugs with the trial firmware I suggest speedsailors use the earlier formal release that are known to work and don't shut the NAVi down for unknown reasons.
I'm with Roo on this one. If you do use Beta firmware and software, you are playing with fire. It's untested for public use - YOU are the tester. If you find bugs/have problems, then no use complaining to LocoSysTech that they lost your record run if you are using the beta firmware. BTW - that is the second 1.6x beta firmware released. My bet is they are still fixing bugs in it.
It's great that the software used to analyse the data is free, but once again, if you use the beta versions then at least tell the developers the problems you run in to and don't get too mad if it frags you data

Thanks Roo for the write up,
I followed step by step and all is fine, I have yet to d/load any data, I hope to do that soon.
Thanks again for your time and effort.
Regards
Hello,
What does it mean when the GTnavi asks "Travel long" Like today when I got in my truck to drive to work so I had some data to play with, when I turned on my Navi it ask me this "Travel long" I selected YES as I was driving about 12kms, I assumed this ws so the Navi could calibrate from where it was GPS initiated last night in Maylands.
Should this happen again do I select yes each time? if so what does it do?
I am about to read the manual again and see if I the duffus can figure it out.
Cheers GT
GT when you turn it on, it will show, "card found," and thats about it, it should do all its stuff from there.
Takes a few minutes to find its Sat group, once this happens it starts to record for you on the card.
Going down off Ardross St at about 3-3.30 to play. :-)
If all else fails, go through the set up as per Roo's guide again.

Travel long. I think that is a question ie "Have you travelled a long way since you last used the GPS?" I've been answering No and it seems to lock onto satellites shortly afterwoods. Took a long time when I answered Yes.
The GT11 seems to be much more careful with its locking onto satellites than the Garmin.
cheers Ian
To calculate a 3D position using a moving satellite, the GPS unit is required to spend some time downloading the satellite orbits, from the data that is sent down from the satellites.
The first time you turn on the GPS, the engine will do this and so will take some time to finally start tracking. When you subsequently turn it on, it will already have a good idea where the satellites are meant to be, and so will lock on sooner.
Since the satellites are continually circling, if you leave the GPS turned off for a long time, the downloaded data will become stale and so will be required to download again. The same effect occurs when you travel more than a few hundred km's -> the downloaded data is not useful. Thus answering "yes" to "travel long" will just make your start-up time longer.
This often happens if you turn on a GPS unit while indoors, you will get a "Travel Long" message and/or a "correct time" message. The idea is that it asks the user to determine what it should do.
Note that on the Fortrex, it will ask if you are "indoors" - dont answer "yes" as it turns off the track logging. ie: next time you go sailing, it probably wont be logging your runs.
Ok guys,
Thanks heaps.
I keep getting a password request when trying to Upgrade Firmware from CD, is this the code that Mal is supposed to email back to me? I have already sent him the email request a week ago, I will send him a reminder email.
Thanks again, any help or advise will be appreciated.
Cheers GT
