Has anyone ever had a new defective unit.
Putting a GPS speedo in my boat, have all hook-ups done correctly, mounted on top of the dash, no obstructions to block the signal coming to antenna.
Still not working, troubleshoter guide says antenna problem.
Last resort is to cut the 3 wires coming out of antenna, & recrimp new ends on them, they are really small diameter wire.
Let me know if anyone has experianced thes problems before.
