I don't recommend this GPS Receiver. I've had a problem on it where the bluetooth part of the device just stops working because a certain part of the chip was not soldered properly from the manufacturer. And this is an issue that has been discussed on message boards as well. There are some GPSlim devices which don't have this problem but make sure that you find out the serial number of the device before you commit to this one. Or else you'll have to tape it around with duct tape to emulate a solder on the receiver to put the right pressure on it to function. Hope this helps.
