  @ Paul N Braida M.E, yes you can swap out from another APM, and I have done the surgery. But you must have a hotair rework tool. And it is rather fiddely to be certain. The compass may be purchased new from Ebay in multiples of 5 for less than one from Digikey.  I believe that the M8N will work as a better solution that the Ublox 6N but not the 7. These GPS/Compass combos  can easily be purchased (Ebay), and your biggest task will be to double check the pinout and the 4 and 5 pin connectors.  I am not sure of the  offset that one would make in Mission Planner as one removes the compass from the PCB. This is a major consideration and config with the Naza M Lite and M V2.

the easiest way is an ext compass, you can use a gps/compass one if you want, that is the APM 2.6

Can I swap out a compass from another APM?

Can I use an M8N compass/GPS unit on the APM 2.5 and configure parameters to external antenna?

You can use external compass

Looking for APM 2.5 compass help. Says bad compass health yet when connected to mavlink shows it working ok. Can compass be replaced?

I'm assembling a robocat 270 motors but I'm not shure if I have to use H or X config, It's have more distance side to side than front-rear, thank's

@ Thomas Stanley-Jones the tool that Cala suggested works great for servo plug type connectors and the pins and sockets can be found just about anywhere-hobby.

As for the DF13 connectors I buy from Digi-key, here is the link to the CONN CONTACT 26-30AWG CRIMP TIN (pins), DF13-2630SCF

and here is a link to CONN SOCKET HOUSING 4POS 1.25MM, DF13-4S-1.25C:

I buy 2-6 pin housings and Digi-key sells up to 40 pin ones.

The HK crimp tool I didn;t have much luck with and I have a similar tool that I paid $130 for and doesn't do any better.

  The best tool I found that works numerous types of pins/sockets(package says

 80 different types of terminals) including the Servo and DF15 is a:

PA-09 Micro Connector Pliers by Engineer that you can get for under $40, works on 32-20awg wire, Molex, JST etc. pins.

Hope this Helps-Don

@Warren Keep in mind that the last firmware compatible with APM are Copter 3.2.1 and Plane 3.3.0.
