Your gps pins are backwards. From top down it should be red, yellow/green, space and black.

@Tim Dickinson The OP has the APM 2.8, which is a clone and it's different from APM 2.5,2.6 pin layout.

@Hugh I don't see anything wrong with your configuration. I have APM 2.8 as well and i've done the same thing. You plug the five-lead connector on top of the GPS sign on your board and the 4-pin connector (which has only 2 cables) exactly at the bottom of it. From what i see in your picture it should be correct. Now i have uBLox NEO-6M GPS and i followed the instructions here to reprogram the module in order to make it work with APM. This and this may also help.

Basic Question, but have you calibrated the compass?

Thanks All,

I tried Nicks suggestion of tweaking the Ublox software and APM21 - no change. It started working when I moved everything back to the APM 2.5 board, did the same update and then moved things back to the APM 2.8 board. 

Thanks again, I got there in the end.

By the way @nikos, what is your Firmware on your APM 2.8 ? i'm currently at the last firmware which is 3.2.1, it seems that to calibrate the motor we have to do it manually. (All-at-a-time) method. i might need a few guide in building up my quadcopter (F450).

I have had to check both boxes (internal and external)  in the mission planner to get mine to work even when I removed the jumper.

Hugh, did you ever find a solution to this? I'm having the same exact problem. Tried the i2C port and the side port by the top GPS port and still no joy. I have a M8N GPS module, and the Arducopter with side ports. I've tried with the J2 jumper in and out. I noticed the head of the GPS is warm, but no light is flashing in it any more.

Could you tell me what boxes your talking about and where I could find them? Thanks.

I too, am at my wits' end with trying to eliminate the BAD COMPASS HEALTH warning on a brand new 2.8. There is very little posted on You Tube that solves the issue. There is a post that pointed out a new jumper on the 2.8 board, next to the GPS port. The poster stated that removing the jumper disabled the on board compass. I found BAD COMPASS HEALTH with jumper in or out, and could not get north to be north on my Apm. I've about had it. I had the same issues with a 2.6 board, that never has flown either. I did the jumper severing thing... nothing helped the Compass situation.
