The reset button worked for me. If you look in the Wiki you'll find a photo of the IMU board, the reset switch is on that board and it is labeled

You also need to be outside, of course. You won't get GPS lock inside.

@Chris,

If you are using the MediaTek GPS, you should be able to get a lock inside the house. I have the MediaTek GPS module attached to both my APs and APMs and can get a consistent lock inside my home which has an aluminum radiant shield in the attic.

 

Regards,

It really depends in your house, orientation and a bunch of other things. I can't get lock in my house due to metal mesh in the adobe-style walls. Others with wood houses can get lock.

I think you could separate whether it's a location problem (i.e. you're in too urban an environment) or whether it's a firmware problem by checking the little blue light on the GPS itself.  I think the firmware change only affects how the GPS communicates with the APM no actually on it's ability to get a lock...

 

so if the little blue light on the GPS is flashing - it's your location.

 

If the blue light goes solid but the APM's lights don't indicate that it has a lock (sorry, i forget at this moment what light indicates a lock), then it's more likely that you need ot update the MTK's firmware.
