Navigate with Garmin-caliber GPS data on the mobile device of your choice. GLO brings you the best of both worlds by combining GPS/GLONASS receivers with Bluetooth® technology so you can enjoy precise position information on your iPad, iPhone or Android device.
The Accuracy of GPS + GLONASS
GLO can receive position information from both the GPS and GLONASS satellite constellations, allowing it to connect to up to 24 more satellites than devices that rely on GPS alone. This allows GLO to lock on to satellites approximately 20 percent faster and remain connected even at high speed. What’s more, GLO updates its position information at 10 times per second — that’s up to 10 times more often than the GPS receivers in many mobile devices.
Set It Up and Go
Using Bluetooth technology, GLO wirelessly pairs to your mobile device. Just set GLO within range of your mobile device, and in moments you’ll be receiving GLO’s position data. It has up to 12 hours of battery life to keep your position on long trips, and charging GLO between uses is easy with the included USB cable or optional 12/24 volt cigarette lighter adapter. The optional friction mount keeps the receiver safe on your dashboard and in full view of satellites.

UPDATE -- JUL 2015 -- Apple fixed the Bluetooth GPS problem in iOS 8.4. I confirmed the GLO works fine on both my iPad and iPhone under 8.4!
UPDATE - MAR 2016 -- The GLO continues to work under iOS 9. I've tested it with iOS 9.02, 9.1, and 9.3 and found no issues.
UPDATE - May 2017 -- Currently using under iOS 10.3.1. I originally bought the module to use with my WiFi-only iPad, but found today it can help my MapMyHike app on my iPhone 6 resolve my workout distances more accurately. The iPhone 6 (and most smartphones) use a hybrid GPS/Cell Phone Tower location system, which is not all that accurate for someone on foot. Added a picture to illustrate the accuracy increase on the iPhone.
BACK TO THE ORIGINAL REVIEW:
I bought my Garmin GLO over a year-and-a-half ago, so I have some experience. I use it with a WiFi-only iPad. The GLO is a small, long-lasting, accurate unit with fast updates and great coverage, but it lacks one simple item I think is very important: A battery level indicator in either hardware or software. The power light on the unit will blink about 20 minutes before the battery dies, but that's not enough, IMO. Luckily from my experience it appears you should be able to count on most of the 12 hours they predict, which should outlast most devices it gets paired with. Buy a spare battery for under $20 or an external battery pack, and you should easily get 24-hour coverage!
Now, I've had some bumps along the road: The first unit I received stopped communicating after 3 weeks, and was replaced by the one that has lasted the last year-and-a-half. I'm hoping whatever made the first one stop communicating has since been fixed in production. I also had a recharge problem when connected to an external battery pack charger, but that turned out to be the charger (I thought it was the GLO for quite some time).
Before writing this review I decided to test the discharge rate of the battery. Can it still last the stated 12 hours? The first test gave me 14 hours and 39 minutes of constant communication with a GPS app on my iPad, so yes! Pretty good for a year-and-a-half old battery. A retest the next day was within a minute: 14 hours and 38 minutes!
I have seen zero compatibility issues with this device. It has worked with every map program and GPS utility I have thrown at it -- Apple and Google Maps, Google Earth, ALK Tech's CoPilot GPS, Waze, and MotionX's GPS Drive to name a few. I typically use ALK Tech's CoPilot GPS, because like MotionX's offering, they store maps right on the device so you don't need an Internet connection. Since I have a WiFi-only iPad, there is no Internet connection when I travel. It will even transparently Geotag my photographs! I do wish Garmin provided a utility that, besides showing the battery level I so desire, would also show standard GPS utility info like what satellites it is using, etc. Historically this type of utility has been a great troubleshooting aid.
I answered a couple of these in the Q&A section, but here are some additional fixes & tidbits:
1) DO NOT USE WITH iOS 8.3 (see ALERT, above).
2) The power switch sensitivity you see in many reviews was fixed in firmware in late 2013. That firmware update was stable by early 2014, so all current production models should have it. Unfortunately I haven't been able to update mine. There seems to be a USB issue that is most commonly fixed by attempting the update on another computer. I only have one computer.
3) The above firmware update also added support for up to 4 simultaneous Bluetooth connections, and gave the GLO the ability to turn off automatically after five minutes if there are no Bluetooth connections.
4) The unit must be powered on to charge. Some people have dead battery issues because they do not realize that. Also, from my experience above, I would play it safe and recharge with a normal 1A power source, not an external battery pack charger. It should normally charge in a little over 3 hours from a normal 1A source, but from deep discharge it may take a while longer.
5) You can geotag your photographs (embed the location where the picture was taken) on a WiFi-only iPad. Simply have the GLO turned on and connected when you take a picture (and have the option turned on under Privacy > Location Services > Camera!) Then you just need to carry the GLO in your pocket.
6) Someone asked what version of Bluetooth it used, presumably so they could make sure they were compatible. I took mine apart, and it appears to have a Bluetooth 2.1 chip.
Hope something here is useful to someone!
With a device like this, I believe it makes sense to provide context for its usage. In my case, it is part of a GPS setup I use for my motorcycle. My setup includes a Samsung Galaxy Note 4 (rooted and debloated), to which the GLO is paired. On my Note 4, I run the 'Bluetooth GPS Provider' app (which is excellent, and allows a degree of GLO configuration), which the GLO connects to, and for mapping software I run Sygic maps. Sygic provides top quality offline maps at a reasonable price (catch them on a sale). In this configuration I find that the GLO works very well. Once it has had a few minutes to warm up, it tracks and updates my position very nicely. The battery life has not as of yet been an issue. I normally keep the unit in my pocket to protect it from the elements.
The GLO and my MotoG make it wonderful for street and trail navigation. By turning off the MotoG location services and putting it in Airplane mode I estimate that I can greatly extend the battery on the Moto G and get extremely high-quality trail and roadmaps using Google Maps, Gaia GPS, and OsmAnd+, both locally and internationally. This is a far better setup than any of the several dedicated GPS units I have considering all of the other features that the MotoG+ has. If you have a decent data phone and you need GPS capabilities than that installed on the phone, this is the hands down way to go. And yes, it is about as accurate a GPS system as you can buy.
problems appear when i use a gps recorder while using waze or maps (or both). a lag is created whereby my position in the turn by turn apps is delayed by (i estimate) as much as 10 seconds. i was using ulysse speedometer as my gps recorder. it seems my phone cannot handle gps logging at 10 hz update rate while using the navigation apps. if i use the speedometer by itself, the speed reading becomes ultra responsive, and the tracks i make really become super accurate.
i solved the problem by using the "gps logger app" instead of ulysse speedometer. gps logger allows me to set the refresh rate to 1hz. this allows the turn by turn apps to run correctly and in synch with my actual position. you may ask why i would REDUCE the refresh rate as the 10hz refresh rate is the main selling point of the glo. this is because, even at 1hz, the accuracy of the glo (upto 1 meter, usually 2-3) is still better than the internal gps receiver (8 meters at best, rarely). so i still get Garmin-caliber accuracy at a rate that my hardware can handle.

I've been using a charger the two times I used it. I noticed that it didn't hold a charge at all. Opened the back and noticed there is no battery!!!Read more
