So this is an Apple iPad mini, 7.9" WIFI only. The non-cellular iPad's also do not have integrated GPS. I picked up a Bluetooth GPS module that works with, so far, every app I've tried, XonOff Road, Google Maps, Polaris Ride Command App, Alltrails, etc. I get great signal in the tall trees, indoors, whatever. Great little GPS unit.

The parts I used:

1: Apple iPad Mini

2: Otterbox Defender Series Case

3: Bluetooth GPS module:

5: Waterproof / Dustproof work box to weather proof the GPS

There's no one answer that fits all applications. You do what you need.

If the box needs a switch and to be wetherproof, there are switches made just for that. Or use a magnetic reed switch. If you need to see an LED, you can extend it through the box, or use one with a clear cover, like this:
