gaffrig performance gps speedo (newbie)
 

i have a gaffrig performance analog gps speedo and when i power up the gauge the needle doesnt move but the red light comes on. everything is hooked up correctly, do the the gaffrig performance analog gps speedo go through the same cycle as the gaffrig precision instrument analog gps speedo or the livorsi analog gps speedo? after about 2 minutes the red light blinks once on the speedo i have, i dont know if thats when the antenna finds a satellite or if if telling me some things wrong.the gauge ,antenna and recall switch is new, someone who knows about these gauges or have one can u please help me. thx
