Dual Electronics XGPS150A Universal Bluetooth GPS Receiver for Portable Devices
The Universal Bluetooth GPS Receiver is very simple to use. There is a quick set up process that includes pairing your device with the Receiver. Once this is done, the Receiver will automatically connect to the device it was last paired with, and you will be able to use it with hundreds of apps that require location information.  The GPS Receiver includes a non-slip pad for use in a cockpit, car or a boat.  The non-slip pad will stick securely to most surfaces, including vertical walls and windows. The Universal Bluetooth GPS Receiver is not waterproof, but it will withstand light splashes when it is seated properly in the non-slip pad.
