Does anyone know if the VX-8R keeps the GPS "alive" even when its not in use (when I'm monitoring a repeater, for example). If so, is there a way to disable the GPS without removing it? The reason I ask this is because I monitor a local repeater on my HT while at work. Before installing the FGPS-2, I used to have plenty of battery life when I took the unit home. Now, the battery is dead when I pull into my house.
