        Wiring up a GPS 
         
         
        
        
       
         Hey all, 
          
          I'm trying to wire up a Garmin GPS system into the connection behind the front light but seem to have run into problems. I've got a 12V supply coming through the wires, and that's going through to the GPS wires but for whatever reason it doesn't seem to be powering the system itself. 
          
          I really have no skill in electricals at all so I'm at a loss - any help would be appreciated. 
          
          Thanks,
          
          Alex.
