Global Navigation Systems, (a.k.a. GNS) has created and sells a plug and play Bluetooth GPS receiver for IOS devices. It’s called the GNS 5870 MFI. (MFI stands for Made for iPhone). I’m not a stranger to testing out and using GPS systems but this is the first one I have used for my Apple product, so I am excited to work with it. Even though I have some knowledge of GPS, I am by no means an expert in this area. There are two things I look for though. One, a quick satellite lock, and two, it just needs to work.
There is no jail breaking required. I’m testing this out on my Wi-Fi only iPad. The Nav App I am using is Co-pilot.
