FYI, I believe the latest version out is 2.04; you can check under your setup to see what version you have, then try to figure the differences out to see if it's worth the $150 to upgrade. Unless you are in an area that was not in a detailed coverage area previously, but would be now, it probably won't be worth it to you to upgrade yet.
