OK..,I'm not able to connect my Phantom to tha Naza software. I don't have internet service at my home but I went to the local library and downloaded the DJI driver (version 2.02) and the Nazi assistant installer (version 2.20) to a USB thumb drive and installed them to my home computer. I followed the "software and driver installation" as per A1 in the Phantom advanced manual. Everything seems to be loaded and the Naza software comes on but does nothing as far as reading my Phantom. I'm using the factory USB cable, changed the dates on my computer to 2015 and 2013 and no luck with that trick. Do I have to be online for all this to work?
I read you tried to install the drivers more than once(the trick of the date is NOT necessary for Windows XP) and then you also try to install the Naza-M V. 2.4.
What I suggest you is to start from scratch with driver 2.02 and Naza-M V. 2.20(that is the LAST version that supports Phantom 1 and 1.1.1). Go in Control Panel and Uninstall both driver and Naza-M assistant.
Reboot your PC and install the driver first.
Connect the USB cable and power-up the Phantom: you should hear the sound of a connected USB device: eventually you can monitor the status of your USB port in the Device manager tab of the SYSTEM icon in Windows Control Panel.
If you do not arrive here, you have issues either with the Pantom USB port or the internal USB cable or the extension cable(that MUST support both data and power:if you can, check this with a different device e.g. a smartphone or a memory stick).
Only when these steps are successfully completed, install the NAZA-M assistant V 2.20 and DO NOT update to a later version, even if you will receive a prompt to do it.
Important note: if for any reason you need to re-install the DJI driver ALWAYS UNINSTALL THE PREVIOUS INSTALLED VERSION first.
I do not remember if in Windows XP there is the option to install as an administrator(option available in Windows 7 and 10):if you see this option by right clicking the DJI driver installation program, please use it.
