it should still work with signal repeaters. Did you map the location first? If this is a new location (i.e. someone else hasn't mapped it yet), then what you want to do is select the floorplan in "Browse Floorplans". You should see a button to start mapping, hit it & follow the on-screen instructions (basically walk around and hit the "mark point" button or the volume up/down button after positioning yourself on the map). once you are done, hit stop mapping & hit yes to upload it to our servers for processing. after some time (maybe 2-5 minutes depending on load) you should be able to hit "Where Am I?" on the home screen to have it track your position.
