Greg,
The 788 on the front is built into the front console and the local Ranger dealership installed a Ram mount so I could take it out of the dash to see it better but this is a bayonet mount, so I'm not really sure how to connect them now that there is a new plate on the 798.
It worked correctly today when I put it in the water but not sure why and for how long. Today, I was moving at idle and at a little higher speed (GT 30 miles/hr). I switched the settings to advanced mode and moved to saltwater mode. Not sure why it goes from working to not working.
