Wrong location with MTK GPS module

Hi,

 

I try to set everything up before the first flight but I have problems with the GPS location.

I get a GPS lock (solid blue LED on the GPS module and solid red LED on the IMU shield), but the position I get on the GCS is wrong, I get one position when I use HK GCS and another totally different location when I use the original AP GCS, both of them are way wrong. I tried updating the firmware on the GPS module as instructed in the APM manual and I get the following error massage :

 

Fail!!(Download) BROM_CMD_START_FAIL

 

I tried the GPS input test, again i get solid red and blue LEDs, I get lon and lan reading, but it says #sats 0.

 

any suggestions?

 

Thanks.
