I have a C140W installed in my sportfisher in Nov 2013,  it is interfaced with a Digital HD radar and the autopilot,  all working very well,  but for the time to acquire a GPS fix.  This is very slow, generally 10 minutes,  but it does always eventually get there. The C140W is bracket mounted on the helm console and sits under a fiberglass hardtop with 3 sides of glass, clears to the rear and using the internal GPS sensor.So my question is should I go for an external GPS sensor up on the radar arch,  or is this an issue with the C140W?Thanks DaveSee More
