No longer works after adding magnetometer and gps

Hey guys I had the apm acting as a stabalizer with out the magnetometer or gps connected and it flew wonderfully. I just received the magnetometer and gps in the mail and connected them as per the manual.. I then reset the apm using the apm setup. however nothing is working every other time I will get a "set sysid_sw_mrev failed" error. I cant configure the radio, or even level the quad... Help?

    Sounds like you've either created a short when you soldered on the mag, or have the GPS plugged into the wrong port.
