I find the GPS receiver inside the rx5940 very slow to fix and also time by time it losts the signal.
There is a way to use an external receiver? I have a bluetooth one (used in my past hx2410), but how I can connect to rx5940?
Thx a lot for tips

Some users have connected an auxiliary antenna for the GPS to improve fix times. It attached to the small round socket next to the USB socket.
For the bluetooth GPS, i suppose it's like any other bluetooth device, make the device discoverable, then push the bluetooth "button" on the today screen (next to the WLAN and GPS buttons) and select and set up your device as a serialport. Make sure the COM port you select for bluetooth is the same as the one under Settings/GPS Settings. Good luck.

however the rx5940 can see the antenna, but the preinstalled tomtom refuses to use the other antenna.
I will try to supersede the default setting but I am concerned I can lost the preinstalled gps and do not have the new antenna.

The internal GPS receiver never seems to be able to get a fix.
I've managed to get the TomTom software to access an external GPS receiver via Bluetooth.
As mentioned you need to pair the iPAQ & the bluetooth receiver, and I've got the GPS "control panel" in Settings/System/GPS set up as: Programs set to COM7, and Hardware set to COM5, and Access "manage GPS automatically is ticked.
You'll need to find out what COM the external GPS talks on, but this setup works for me (at the moment)

I tried both solutions and. they worked the first time.
Then after switch off the PDA the next time I did have any antenna neither the internal nor the external. I had to pair again the external and do all the process.
I decide to roll back to internal, but is terrible!!
If you can help me, please do

Have you tried changing the Hardware port in Settings/GPS
You may need to try each COM port in turn to see if you can keep the connection.
Also turn on the external GPS receiver and then count to 10 before launching the TomTom software.

1) Install the GPS firmware update from this site.
2) Install the daylight time saving fix from this site. Someone mentioned that it improved GPS lock speed. I can't be definite but it SEEMED to work for me as well.

Solution: delete the CFG files ("Reset TomTom to factory settings") and during the first configuration specify the Bt receiver instead of the integrated receiver.

but the rx5940 comes with tomtom already configured. I cannot specify any device.
I have tried the other tips, but no way !!
Once the ipaq is off-on then all settings shall be done again.
I was thinking to disinstal the preinstalled tomtom and installing another tomtom, but is it possible?
