Thourough reassembly info

Which one did you do first: Did you install ActiveSync 4.5 first, or did you try installing the driver first?

The best way to do this is as follows:

1. Download and install ActiveSync (4.5 is what i use both at home and work and it works great with the NEC 900 and 900C's.
2. Restart your Windows XP Machine (I assume you don't have Vista)
3. Next, follow the instructions for the installing the NEC 900 usb drivers (these drivers should be installed AFTER installing ActiveSync... (it seems to work that way without problems for me).
4. Next, restart your xp machine again.
5. Now, connect your NEC MobilePro 900 to your Windows XP machine, and it should perform smoothly.

If this does not work for you, you can contact the folks at usedhandhelds.com, they sell and repair, as well as provide support for these machines.


Hope this helps

I had the same thing happen to me.. The site below will fix you up just follow all the steps.. Some things are worded slighty different in XP so just use common sense for those things..

Just make sure to set your Computer as HOST when it asks.

Also I could not find the mobile devices or something like that tab in Windows XP but it still worked.

I don't believe that I've seen that..how did you 'send' that information?

Are you using the NEC Mobilepro 900c drivers? I'm sure the drivers are different. YOu can find the XP drivers here: http://hpcmonex.net/nec900/files/soft/nec/activesyncusb.zip In addition, you should make sure that you have Activesync 3.8 or older. You can find it here: http://www.hpcfactor.com/ftp-root/software/microsoft/activesync/activesync-38/MSASYNC.EXE

I have a 16gb CF card works fine, cost $79.00
