Raytheon Chartplotter 420 - No FIX
I had this problem and fixed it by replacing the small 'watch' battery (CR2032) in the unit.
Remove the two screws to remove the threaded base. Remove the six small screws and pry the unit apart. The battery is 'stuck' to its electrodes so use a blade and luck to get the old one out without causing damage.Hold the electrode with a needle-nose so that they don't break off.

Well...that would hav been too easy and simple!
The 420 has a DEDICATED GPS input and cannot post a position from any other NMEA device so you will need to contact Raymarine to find an APPROPRIATE new antenna AND connector...or just get a new plotter with all the good stuff built in.

|wduncan50||The only connections I see off of the antenna are all in a single cable going to the plotter and the connection there all look good.|

|camaraderie||Is the ground wire ON the antenna in good shape? This should be checked as well.|

Raytheon RC420 GPS - no fix
I have a Raytheon RC420 chart plotter that powers up but gets no GPS fix on the sats. I checked the connections on the unit to the GPS antenna and they look good. Do I need a new antenna or is there something else I need to check?
