Not sure this is the right place for this question,.

Considering a "keyhole" backup camera (to be plugged into Dom's DVD-Nav unit)



Car is TSX so no keyhole, so to put this in requires drilling a hole ?
Anyone familiar with this step, input please

 

ive seen people drill a hole in the license plate area...above the plate. its noticeable if you look directly at it but its not noticeable.
