I have been told my A.P.I.M. for my 2012 mkx needs replaced.....my screen is blank, my phone,radio, and backup camera isnt working......i tried resetting and it worked a couple of times, but now it wont. Can anyone hep me on any costs for this part and/or any ways i can save a bit of money on repairing this, since im retired and on a rather fixed income...im in Illinois!...anything will be appreciated!!
