Did my survey and everything looks great at this point. few things came out before the survey report. SR310 - 2008 with 6.2 seacore and AXIUS.

Engine data not showing in GPS. newly installed Garmin 74CV + Transducer. How do i get the data form the Smartcraft to the display on the garmin?
  • Newly installed Marine Radio - GX 1600
  • Newly installed TV antenna
  • Newly installed Garmin GPS 19x HVS
Any additional thought would be much appreciated.
 
That Garmin unit uses NMEA 2000. You need a gateway to convert from SmartCraft to NMEA 2000. such as this one. I believe Mercury also makes one.

thank you for the update. How much should I be expected to pay?
 
The mercury gateway itself can be had for a little over $400. Add cables, and installation, and you're probably looking at a boat buck when all is said and done.

Here's some hardware porn

are there alternatives? what if i change the Garmin to some other model, would it support the Smartcraft to NMEA?
 
Yes there are alternatives. Jump in and get to googlin' lots of info out there.
