I bought the Garmin GLO2 for use with a six year old non-cellular iPad to provide navigation. I first thought Apple would allow the GPS signal from an iphone to be sent to a non-cellular iPad but of course they do not and there is no way of using the iphone GPS data that Apple is willing to disclose. After seeing a couple of other solutions I went for the Garmin because of their GPS history and experience.The instructions are not comprehensive. The unit pairs easily enough over Bluetooth. The blue LED goes from flashing to solid when it is paired.The flashing green LED took five minutes to find a satellite fix the first time I turned it on. When it had found the fix it turned to a solid green.On charging the amber light flashes until the battery is fully charged .If like me, you put the device on to charge and it’s hunting for satellites then the green and amber lights flash alternatively. It’s both charging and hunting for satellites. Makes sense. But the instructions say that green and amber flashing alternately means you either have a faulty battery or a system error. So there was five minutes of buyers remorse until the green light turned solid. Now there’s a solid green and a flashing amber until fully charged.After pairing I brought up Motionx-GPS – surely the best navigation app on the market at the moment. I use it for navigating around on some of the nearby lakes. The app allows you to choose the method of location fixing: GPS, WIFI or manual. I turned off the WiFi and then I hit the GPS soft button and within a couple of seconds the signal strength for GPS appeared and fixed my position within 98 feet (the app said). I’m not sure where the accuracy number is coming from. However I have left the tracking function working on the app for 30 minutes and the app is showing movement of about 40 feet in a straight line even though the device is sitting on my desk.In terms of the specifications I would probably have given it 2 stars. Cold Start 60s – no – more like five minutes. Accuracy 3m – no – 30 minutes of use shows a track deviation of 40 feet and my app, however it is getting the accuracy data, says 98 feet.BTW turning on Wifi on the iPad improves the accuracy to 33 feet. I’ll take the unit on road trip to see if that changes as soon as we are out of WiFi range and let you know the result.But for $99 i now have a working navigation system on a big screen and a new use for an old iPad. I’m happy enough it works with a non-garmin app.Edit on October 15th 2019 – I’ve used the GLO 2 for a few months now and it’s performed well. For whatever reason the Motion-X app now shows the accuracy is 16 feet. I’ve written to Motion-X asking them how they calculate the accuracy but I’ve not received a reply. I agree with one of the other posts that it really needs an accurate battery level indicator. I would pay an extra $10 if the device had this. On another point I don’t understand why Apple doesn’t allow the export of the GPS location over Bluetooth – any clever people out there who could explain if this is achievable?

After initial setup with ipad mini 6, this unit connects to it automatically via bluetooth. My ipad is wifi only (non-cellular). If you either a) download the map content that you need before taking the trip, or b) connect to your phone’s hotspot, you’re good to go! This automatically sends gps signal to google maps app. Super accurate too!

I have used this Garmin glo to back up my nav systems on the ground and in the air…along with ForeFlight and taxi diagrams it really helps..on my iPad I can see where I am on the ground or on a approach…or enroute..at all times..The battery life is pretty good..and it’s Bluetooth so you can still use the airplanes wifi along with it..in my case we have wifi in the jet above 10,000 ft..i also have a stratus 2, but it’s a lot bigger and doesn’t fit in the headphone bag so well..you can also plug it in on an AC outlet if you have one..Rechargeable batteries are fairly cheap..so of it starts to fall off for duration..just order another one..can’t remember the price but think it was less than 20 bucks..The unit is fairly inexpensive compared to bad elf pro or stratus..the rubber base mount always stays where you put it..on the glare shield..so if you are like me and have internet anyways..this is all you need..I am not saying this Is for everyone..if you are flying a C-172 heavy Sky Chicken..you prob want WX like the stratus gives you..and traffic..but for those who already have all that other stuff..this does the job and fits into the side pocket of your headphone case…In my case..I also ordered the belt clip..prob a waste of money..but keep it in my flight bag..my last thing to say is it works great and lasts a long time!..HaHa..

Great peice of gadget for your IPad flight application

Is very accurate
