Guide Review - Bad Elf GPS Review: Easy GPS Upgrade for iPad, iPod
Apple hasn't placed GPS chips into all of its popular portable devices, and that has created an opportunity for aftermarket producers, such as Bad Elf, to provide GPS capability. The original iPad and iPad 2 "Wi-Fi" models do not have built-in GPS chips, for example (see much more on iPad GPS). The iPod Touch also lacks GPS. These devices can find your location fairly accurately using WiFi positioning, but that's not good enough for turn-by-turn navigation apps, for example, which need a high degree of accuracy, and the ability to work when far away from WiFi signals.
It's understandable why Apple doesn't put GPS chips in devices that don't have mobile 3G connectivity. Many navigation apps require always-on internet access to download maps and to conduct address and services searches, for example.
The GPS add-ons are for those who still want GPS despite the limitations of non-connected devices. I plugged the Bad Elf GPS device into an original iPad WiFi model and tested it with the free Waze turn-by-turn navigation app.When you first plug the Bad Elf module into the iPad, it prompts you to install the free Bad Elf app, if you don't already have it on board. The app is very simple, but performs the important function of letting the Bad Elf unit talk to its home servers to check for firmware updates, and it shows you GPS connectivity and signal strength.
Once you have the Bad Elf connected and the app working, it's a simple matter to switch to any of the many compatible apps that pick up the Bad Elf GPS signal.
Bad Elf was quick to get an accurate GPS fix, and worked smoothly with Waze to provide me with accurate spoken turn-by-turn directions to my destinations. I turned the iPad's WiFi off completely in settings to make sure the unit wasn't getting navigation data from WiFi locations as well. Waze must have cached my local maps, because its maps kept up with me as I traveled my local metro area. It would no doubt need access to WiFi or other connectivity to upload fresh maps on a long trip.
You can determine GPS fix status by observing whatever the individual app provides for monitoring GPS fix, or you can use the Bad Elf's green indicator light - blinking for getting a satellite fix, and solid on when GPS-locked.
You may charge your Apple device even while using the Bad Elf because it comes with a micro-USB port and compatible USB cable.
Overall, Bad Elf is a good and relatively inexpensive solution for bringing solid GPS capability to your Apple iOS device. There is no need to jailbreak or otherwise compromise your Apple device to use the Apple-approved Bad Elf.
