Using external GPS in order to improve GPS connection

[mdahms]

Hi,
I'm using an iPhone 4GS and an iPad 3G with Laptimer & Trainer. I would like to improve the GPS capabilities of the iPhone and iPad, therefore I have bought an GPS BT receiver (GNS 5870 MFI).
Both devices perfectly connect to the GPS receiver via BT. But in Laptimer I cannot connect to the GPS receiver but keep on the internal GPS.
How can I override the internal GPS?
Thanks and best regards,
Matz

Hi Matz,

The GNS is not directly integrated into LapTimer (like the GPS sensors you see in the Sensors List are). As any standard Apple certified GPS it simply replaces the internal GPS. For LapTimer it still appears as "Internal GPS" as LT has no chance to recognize the difference. Oddly, GNS doesn't offer a interface for direct integration.
