We all know that the Reach devices can’t connect directly to iOS devices (i.e. to use built in maps or other navigation apps), but reading GPS World yesterday I came across this device by Eos Positioning Devices:
No indication of price but the RS+ or RS2 should be able to connect to the Eos Bridge and the iOS device connect by BT to the other side. Not sure if there are any similar devices out there, but if the price was right it would be a great solution to access accurate GPS positioning to native iOS apps.
