I have the Rino 530hcx and love it. What questions do you have? Do you know that you have to have an additional cd with either street maps or topo to get more detail? Shoot some questions and I'll keep an eye on this thread and try to answer them. I started with the yellow Garmin eTrex then Rino 130 and finally upgraded to the 530hcx due to it having usb connectivity. Once you start to load maps you will appreciate the usb connection.
