If you see NODATA text in the top left corner in SeeYou Mobile, this means that SeeYou Mobile is not receiving any data at all from the selected COM port.

Note that this is different than when it says BAD. BAD means that there is data on the COM port, but the satellite reception is not good yet. Tipically all you have to do in this case is step outside with clear view of the sky and wait a few minutes.

Back to NODATA. Proceed with this steps:
1. Menu > Next > Input
2. Make sure "Serial" is selected as your input
3. Press Port Settings button
4. Setup "COM 1, 4800, 8, none, 1, DTR and RTS not checked" - consult the documentation of the GPS to be sure which settings are correct!
5. Finish with OK, OK until you are back on the map view.
6. Does it say BAD or OK or 3D/7 now?

If not, what does it say? If it is still NODATA, you need to find the correct COM port and baude rate:
7. Go to Menu > Settings > Hardware > Terminal > Port Settings
8. Change the COM port (press OK each time) until you see something coming through. If it's readable, your fine. If it's not, please send me the Terminal log which you can do by pressing the Save button.

Hello
I bought a MIO Moov 580. I unlocked it and installed See You Mobile 3.1 RC2 on the storage card.
I did all the procedure below but I still have the NODATA message whatever the port I select.
What else can I do to make it work?
Regards

Please try COM 2 and COM 4, baude rate 56000 and 57600.

I know this problem and spent many hours to fix it,
I had a MIO MOOV 500 which works correctly and a MIO MOOV 560 which didn't work !!!
NO DATA
I understood now why :

the com port should be COM 2 and Baud rate 57200 but if your MIO doesn't work, you should remove the file smartST_CE in program file and the GPS in See you will work ...
I don't know why but it seems that even when smartCE .exe is not launched , it uses the port com from the GPS
Let me know if it fixed your problem

Yet I fear, that it would break the normal mio software on the device.  Which is no problem if you want to use it only for SeeYou mobile, but would become a problem when you want to use it for road navigation again wont it?

Yes, however. We did test the a Mio 5xx device ourselves and both car and SeeYou Mobile navgation was working. There must be a way to make it work.

This just underlines how different PNA devices are.

True 

I can understand why though...   They all want to push their own standards, and prevent the competition's software from working on their device.

We'll. It's an up-hill battle if they try to do this. Devices which can run SeeYou Mobile easily will be reccommended for glider pilots (let's not forget paragliders and hang-gliders here as well). For example - HP made a pretty mess with its 314 as a road navigation device. But because it is a REALLY good hardware glider pilots have bought almost all remaining units worldwide.

If they are worried about users using other software on their devices they should focus on their software and make it better than competitior's software

In fact, when you use the unlock method from http://navmanunlocked.wikispaces.com/Unlock, the unlock process create a Autorun.mscr in the "Program Files\Unlock" directory. This file script start the MioMap 2008 program then kill it. This method is the only solution today to put the device in the maximum blacklight (using the miomap pref). But by this way, the GPS device stay locked by the CLMApp.exe process who stay in memory after the miomap kill.

You can modify the script to correct this stuff like this :
Run("\My Flash Disk\Program Files\Navman\SmartST_CE\SmartST_CE.exe")
WaitFor("SmartST_CE", 2)
Kill("SmartST_CE.exe")
Kill("CLMApp.exe")

I have a Mio Moov 580 and all work fine ! SeeYou + MioMap 2008 + other stuffs

Hope this help...
