Adding GPS support to a Wi-Fi only iPad I have been reading on this, and so far the option I found is:


Garmin/XGPS external Bluetooth GPS receiver


And that is it. Are there any other alternatives?

I’m curious if an Android or iPhone could be used to share its GPS. I should have gotten a Wi-Fi + cellular iPad, but thats a different story.
Using External GPS / GNSS With iOS

This requires :


The external GPS must be a Made for iPod (MFI) certified External Accessory (EA) that support iOS (has the Apple authentication chip) via a Bluetooth connection to the GPS
Requires that iOS Core Location Services be overridden by one of two methods so that all apps on the iPhone/iPad will use the external GPS.


1) Use of an app such as EOS Tools Pro that receives location information and overrides iOS Core Location Services.
2) The External Accessory (EA) itself somehow overrides iOS Core Location Services.
I do not understand how this is done.
Only devices made by SXblue https://sxbluegps.com/products/gps-gnss-receivers/ can do this MFI magic AFAIK.



I have found only a few GPS manufactures that support iOS:


BadElf (lower accuracy but lower cost)
EOS https://eos-gnss.com/product/arrow-series/arrow-gold/
BlueStar (rebranded EOS devices) http://bluestargps.com/index.html
SXblue https://sxbluegps.com/
EOS (BluStar is EOS Arrow 200 I think). All these EOS devices support iOS:

Sharing Android GPS with an IOS Device

I have no idea if this works.
