Question about GPS
The radio is connected to the security system, the system must reconize the ignition key,engine computer and the radio for vehicle to crank.I think the ford dealer can bypass this feature with there factory scan tool.You may also try calling your local radio shop , they may know a trick or have the quipement to take care of the issue.FYI, never cut a wiring harness when installing a radio.There are aftermarket pigtails to adapt almost any brand of radio to any kind of car.Make for a good connection and a neat job.If you must cut a wire it should be soldered together and heat shrinked.Never use but connectors or the the old swist technique,that will be a problem for another day and can be a fire hazzard.Good luck.

It is not advisable to cut off the original harness but to keep the connectors intact while a coupling harness extender to connect external systems can be purchased. This will prevent the loop connections from being cut off and thus produce similar problems.
I suspect there is a ground connection break to the harness that needs to take the circuit back.
Please check with the cut off harness if there were wires that looped or connected together, if so have it reconnected. Also the black ground must be connected to ground if there is no negative on the wire as it might be the ground from the old set body mounting.
So please get back to where you started , check the cut wires or have it wired as original but have your stereo connected with slits on the power and ground wiring.
