  If your Raymarine Radio isn't getting a GPS fix, here's what to check: * A GNSS (GPS) receiver is required to obtain a position fix. Your product may include an internal GNSS (GPS) receiver, if not then an external GNSS (GPS) receiver such as the RS150 is required. There may be no GNSS (GPS) receiver connected. * Depending on variant, your product may include an internal GNSS (GPS) receiver. The receiver may or may not include an internal antenna. If your product’s internal GNSS (GPS) receiver does not include an internal antenna then you will need to connect an external passive antenna to the GNSS (GPS) / GA150 connection. There may be no antenna connected to GNSS (GPS) receiver. * For optimum performance, external GNSS (GPS) antennas and GNSS (GPS) receivers that include an intern...
