How I enabled GPS in Dell 5720 Broadband card in my Dell Latitude D630 laptop
Tony-K
I recently learned that the Dell 5720 broadband card in my Dell D630 laptop has a GPS unit built in. The GPS was inactive by default and was turned on by setting a registry key, HKEY_LOCAL_MACHINE/SOFTWARE/Novatel Wireless/NextGenCommon/GPSHWStatus to 1. After rebooting, the system automatically detected the GPS and assigned it to COM Port 7. On Microsoft Streets and Trips 2010, I went to Tools/GPS/Configure GPS Receiver. I just selected COM Port 7 and it worked right away.

Great tip, Tony. Thanks for sharing it.

Agree!

How did you discover the latent GPS capability?

I wonder how many other laptops are so endowed...

The GPS functionality would be part of the WWAN cellular card, probably a mini PCIe plug in. These are an optional extra on some more recent laptops and other devices. Not all are GPS capable and finding the right procedure to enable the ones that are can be quite tricky. Congratulations!

Do you know the particular cellular card the Dell 5720 uses?

I have the same card, same computer. The GPS is recognized in device manager on Com9 yet, Mappoint does not see it. I have tried changing the baud rates to 4800 as well as 9600 to no avail. Any suggestions?
tcassidy
You can not change the baud rate using Device Manager. This has no effect whatsoever on the hardware. If the device defaults to other than 4800 bps, you need GPS Gate. You can set it to find your GPS and provide a COM port with a data rate MapPoint will recognize.

This assumes the GPS actually puts out NMEA formatted GPS data.

Sorry, I guess I did not make myself clear... I change the baud rate on the port in device manager - not the actual gps' baud rate (good catch). MapPoint does not see the GPS even though it is "seen" in device manager. MapPoint says not GPS found
tcassidy
That is perfectly clear. As I said, you can't change the actual baud rate of the GPS device by altering the COM port baud rate with device manager. That setting is a throwback to the days of real COM ports and does not control what the hardware (the GPS device) is sending in any way.

Unless you have software that can control the hardware directly and instruct it to output 4800 bps, you must deal with the data rate that it does provide. That's where GPS Gate comes in. It can take your GPS data from the device (assuming it is NMEA) and output it at a speed that MapPoint can use (4800 bps).

Why in the world would I need GPSGate? MapPoint is supposed to pull the 0183 signal straight into itself and plot your position on it's own map. The problem is that the GPS is not being recognized (BTW I used GPS Postition as well to see the 0183 strings and it too would not see the GPS).

You'd need GPS Gate to act as a baud rate converter.

I don't know what 'GPS Position' is but it is quite possible that software also needs to know what speed the data is coming in at (the bit or baud rate).

GPS Position allows you to select your GPS' baud rate from 1200 - 128000 and displays the outputs
tcassidy
That wouldn't be very useful if the bit rate of your GPS is less than 1200. What about 9600 or 4800 bps, both very common rates.

As I mentioned Terry, I tried them both. No luck for any output.
tcassidy
Oops, I got my numbers wrong!!

Did you try the other common ones like 115.200, 57,600, 38,400. And I don't mean changing those numbers in Device Manager either. You must make the change in your program. Unless it automatically scans them all looking for a matching signal.
