livorsi gps speedo ?
 

my livorsi gps speedo is acting alittle strange. when it powers up it does it's diag. thing and seeks the sattelite signal but sometime when i'm running it seems to not read like maybe the antenna isnt picking up signal? could it be the battery is starting to go bad in it?

Good thread a couple years ago here: http://www.offshoreonly.com/forums/g...problem-2.html

U need a new battery about every five years.
