Re: Do I Need an EPIRB?

I think the first question is easily answered; the VHF needs input from a GPS to do its job (range to this; bearing to that; etc). Since the radio lives below deck it will need a GPS antenna in addition to the GPS 'chip'. Since most boats already have the GPS data available, the manufacturers don't bother to include any GPS functionality with the radio. Most likely the extra circuitry would be wasted when the skipper hooks up his existing chartplotter (via NMEA 0183).

It's a guess, but I think it's a good one.
