It keeps freezing all the time and I have to pull the battery out to get it working again, then I downloaded a bunch of frequencies and tried to import them ( instead of manually having to input them) when I tried to connect to the PC there was some problem with the communications between the 2, I could connect but not import (I called Yaesu and they confirmed that my version of windows should work) I downloaded some type of driver and it still didn't work so I gave up and manually typed it in. The Gps is just a bare bones kind of deal, I had more functionality on the very first Garmin handheld Gps I bought back in 1996 than this thing does.
The user friendliness of the menu and submenus was obviously designed by a techno nerd with no thought of how the average Joe would find it cumbersome to navigate.
Looking back I wish I had bought the sportys with the NAV CDI feature instead of the Yaesa 750, it has the big dial pad for fat fingers.
