External GPS device vs Internal GPS
I have an IPAD 1 with wifi and 3G that has an internal GPS. I am a pilot that uses the iPad for secondary tracking of flights. The internal gps works ok during low altitude flights but seems to go out and back in as I climb to higher altitudes. I understand that there are a few devices like the Bad Elf GPS that will work at higher altitudes and at greater speeds. But the reviews I have read state that you need to have an iPad WITHOUT gps for it to work.
Is there a way to disable the internal gps?
Is there a flight map out there that will allow you to use an external gps devise to over ride the internal gps?
Is there another product similar to the Bad Elf GPS that will work with my iPad?
Is my only solution is to get another iPad without gps?
