Wanted Input needed on gps sonar combo

[Waynes World]

I am in  the market for a gps sonar combo that will communicate with a raymarine 1000 smartpilot, which probably means it needs a nmea 2000 net work connection. im looking for a unit for under a grand. I have previously used lowrance and am looking to switch. I like the raymarine dragonfly but am not sure if it will communicate with my auto pilot. I fish lake Ontario so a dual frequency transducer would be ideal. Any advice would be welcome, thanks Wayne
