Just bought a Navalert and got it yesterday. While waiting for my download file (Im not sure why it cant be accessed without it being emailed), I was looking at the V 1.0 user manual that came with it. It states to check the website for updated manual. It appears there are other functions that you can access on the unit that are not on V1.0 and it would be cool if someone could at least just add the extra info in a post, or update the website.
