Hi,

Are you talking about a portable one that plugs into the cig lighter or the headunit?

Then; is it an after market gps? If so, check the fuse at the back of the head unit.

Id still be checking a fuse...the one in the fuse box, not sure what it would be called?

Yep, check the fuse for the stereo, should be in the manual if you are not sure. I don't know if these carry a fuse at the back of the unit. That would be my first step.
