[DM] [CA11] Integrating GPS sensor to E80 with NMEA

[robr]

I have an E80 MFD with RS125 GPS sensor that is intermittently indicating NO FIX. I've tried replacing the battery in the RS125 but still get NO FIX (intermittent). I'm considering replacing the GPS sensor with a new sensor that uses NMEA 0183. I also have other instruments such as ST60+ speed, depth, wind and ST7000 autohelm. I'm assuming these are connected using SeaTalk, but need to confirm (it's a 2009 Hunter 38 sailboat). Can I simply connect the new GPS sensor directly to the MFD using NMEA 0183, or do I need to get a NMEA 0183 to SeaTalk converter and connect the GPS through the converter? Also is there anything else that might be causing the intermittent NO FIX? Thanks.
