I have a Garmin 160 bow mount, and it is impossible to use when I am running the trolling motor.  If the trolling motor is higher than 40%, it shuts off the Garmin.  If it is less than 40%, then the screen dims.  I have the interference setting on the Garmin set to 98%, and it still doesn't help.  Is there anyway to fix this?

I have a Tuffy Esox Ltd, and all of the wires are joined and then run to the batteries.  Should I run a new set of wires to a seperate battery (I have 3 batteries)?  If so, what is the easiest way to do this?

Thanks,

Scott
