Re: radio for safety
Do you have a GPS? Do you plan on connecting the GPS to the radio?
I've got a Lowrance HDS-7 GPS/FF and chose the Lowrance LVR-880 as the connection between the two was the easiest. I could not find another VHF that used the NMEA 2000 bus.
By them being connected, the GPS will update your position to the radio constantly.
