Dual ElectronicsXGPS150A Multipurpose Portable Universal Bluetooth GPS Receiver | Wide Area Augmentation System, Black

This XGPS150A works well, it allows my non cell enabled iPad Pro to work as a mapping device, such as with Google Maps. I still need to tether the iPad to my cell phone to get the maps. Apple does not allow its phone to send GPS information to a tethered iPad. If an iPad doesn't have the cellular hardware, it lacks the tiny inexpensive chip that would enable GPS reception. There used to be an app that would allow the phone to send GPS location data to an iPad but that app has been removed, rendering non cell enabled devices pretty much useless for GPS. Not only does the XGPS150A restore GPS function, it seems much more accurate than cell phone GPS. There is a disk displayed around the mapped location indicating the uncertainty of the mapped location. That disk is much smaller with this XGPS150A than it is with the iPhone location mapping. This 150A not only places me on the correct side of a divided highway, it follows as we move into an exit lane. I believe location accuracy is claimed within 10 feet and it seems well within that. We used it on a 6 hour trip so I can tell you battery life is longer than that. When I ordered it I had the idea it was much larger than it really is. The unit is small, it weighs 48g and measures 2.2" square and 3/4" thick. It has a molded in loop on the back for a strap and that adds a bit to the thickness, otherwise it would be thinner. It comes with a Velcro type strap and a handy rubbery molded pad so it stays put on top of the dash. Others have noted that the charging cord can't be used while it is in the rubbery pad. That isn't really right because you can put it into the molded pad tilted with one edge up. It is still held well enough that it stays put on the dash but can still be charged.My previous iPad mini was cell enabled and I didn't realize when I bought my current iPad Pro that the non cell enabled iPads were so GPS crippled. It makes little sense to me that a tethered iPhone can't send GPS location to an iPad. Anyway, this XGPS150A restores the GPS function and it seems to markedly improve on the iPhone's location accuracy in the process. The difference on this 150A model and the next higher one is this will connect to just one device at a time.There are just 4 status LEDs on GPS antenna. There is a downloadable app that gives information about which satellites are being used and an indication about position and accuracy, but that accuracy is indicated with a nonspecific word such as "good" but not in the much better way such as an estimate in feet or meters.It comes with a charging cord but no wall charger. It does have a cigarette lighter type plug for 12V charging.I'm happy with this GPS receiver and would purchase it again.

This is the coolest thing for my iPad. I wish I had purchased the 3G iPad that comes with a GPS Receiver, but since I didn't, this device makes it possible for me to use many GPS enabled iPad apps. Some apps will not install on the iPad if it is not 3G even if you have this device so use caution when buying the apps. I do experience an issue when switching between apps while I am using this device. The iPad seems to lose the GPS even though the utility with this device shows that it is clearly working. I DO NOT believe that the issue is with this device, I believe it is a software issue, but it's something to be aware of if you use this. The remedy is to shut down both applications (if you can figure out how to do that on an iPad) or shut the iPad off and then back on which is what I do. It doesn't take very long, but if you are in the city and using this for navigation and your turn is coming up, watch out!! Again, I don't think it's the device's issue. I use this with the CoPilot navigation app and the What's Next app and a few others.8/7/2012 - I took this device on a 2400 mile trip and it worked great with my iPad 2 and CoPilot and other apps. One thing I learned about my iPad is how to actually shut apps down without rebooting the thing. I'm a pretty tech savvy guy so when someone asked me about shutting the app down and restarting it I had to say I didn't know how and eat a bit of crow. Shoot, for all of you who have iPads and don't know, double-tap the center button and little window at the bottom opens/raises up and shows you all the apps that are running. Hold your finger down on one of the app icons until they start shaking and have a red minus sign on them. Touch the minus sign of the ones you want to shut down and viola, you are done. Click the button once to get them to stop shaking, click again to exit. I thought I was shutting down all my apps when I rebooted the darn thing, but no. When I double-tapped that button the first time, EVERY app on my iPad was running because at one time or another I had opened it and never closed them. I guess you learn something new all the time even when you thought you knew it ALL already.
