I don't know if this helps but the turn signal relay has a line that is switched from the ignition key (on xs400). It may prove to be the easiest place to splice into. always make sure to fuse any connection you make! use as low a rating as possible (ie. if the gps requires 1.6 amps then 2.5 amp fuse would be more than enough)

Epic Fail!!!
