There seems to be a major problem with iOS 6 and external GPS's devices such as the DualXPS 150, Bad Elf GPS. Losing a lot of data, didn't have that problem with iOS 5. Pilots beware of using these devices with iOS 6. One software vendor said to try resetting device and that might work, didn't work for us and vendor said looks like Apple will have to fix on upgrade. Anybody else out there having problems?
