Venue 8 Pro GPS?

I think I found the source of problem. You probably have dell driver updater set to download new drivers automatically. So did its job - found new driver (exclusively for 3G version) and installed it. So that's why you see this driver on your device list. But unfortunately - you don't have GPS receiver in tablet. It's a pity that Dell has not decided to add GPS to WIFi version.

Sorry for my bad english but I really hope you understand what I tried to say.

Best.

All I say in this message is just a creative idea.
I do not encourage you to implement ideas described by me.

I found picture of DV8P motherboard:

It's WiFi only version. Notice, that next to white sticker below the processor (the black square) there's LTE mark. I guess that's the spot where GSM/GPS module is placed in 3G versions. If so, we should be able to buy and insert this module on our own. The only question is which module is placed in 3G version...

EDIT:

There's better pic of LTE mark:

I found the right 3G module: http://www.sierrawireless.com/productsandservices/AirPrime_Wireless_Modules/Essential_Modules/MC_Series.aspx. It's MC8805. And it does have GPS bulit in. 

@up: I found one: http://www.dx.com/p/globalsat-bu-507-s4-micro-usb-gps-receiver-black-263821

Well, now, that raises an interesting idea for the DV8P: a GPS dongle accessory that could be used on trips, inserted into the tablet's microUSB port. :)

Yes, I also think it's very interesting.

So, please do not disassemble your devices :)

There is no hardware GPS present, per se, but there is what is called "aGPS." aGPS uses your computer's IP address to approximate where you are but only to an accuracy of about a couple miles.

As far as I know, aGPS uses mobile network to localize the device. Technology you described is called WPS (WiFi Positioning System). And that isn't a feature of device but of the Internet.

I never heard about Navionics (maybe that's because I never sailed). I checked out their website and seems that there's an option to download maps and work on them without internet connection. So if You use offline maps - you don't need WiFi connection.

But, You'll need GPS signal to track your position, because V8Pro does NOT have bulit-in GPS reciver. The best choice will be external bluetooth reciver or, if you have an android phone with GPS, you can use app called 'GPS2BT' - I use it and works fine. If you have any trouble to use this app with V8Pro, please contact me.

Dear Mr Bronze,

            That is not a good solution. Smart phone can use gps device in their hardware. I would like to suggest to dell to insert gps device default in all DELL Laptops.
