Not sure anyone can help me with this but i'll try to explain my problem best i can.
I recently bought a HDS7 gen3 and Point 1 antenna. I have been trying to set it up to overlay the radar on the map but i constantly get a "radar overlay invalid" message on the screen when i am on the water. I have been in contact with tech support, and have tried everything they suggested which ill mention here:
1.Thought it might be a defective point 1 antenna but i got another one and it still does it
2.Thought it might be the new Gen3 unit. I dont think it is because i tried swapping out my Gen3 unit with a older Gen1 hds 5 that i use at the back helm, but it does it too when it is mounted where the gen3 is (front helm)
3. I have a front and rear helm. the front has the gen 3, and has a 2 foot cable to the NMEA T connector. The rear helm has a 15 foot cable to the T connector. If the front one is disconnected and the rear is connected, the Radar overlay DOES work. If it reconnect the front, it stops working. does not matter what unit is connected to it.
I thought it might be the cable on the front one, or the T. so i changed both the T and the cable, but it still does it. I tried moving Tees around, makes no difference.
4. The radar overlay works just fine on the trailer in the driveway all day long. As soon as I am on the water, even just at the dock, it stops working immediately. always works on the trailer, never on the water.
The point 1 heading sensor works good and the GPS on it is always working. i got a 5% on the magnetic field calculation on it, and it has calibrated properly.
I am totally at a loss here. it makes no sense to me why it works on the back but not the front and why it works fine on the trailer but never on the water. short of changing my entire NEMA2K wiring for the whole boat, is there any other reason it would do this? What a nightmare. I would have hoped that $3000 of electronics would be a little more turn-key than this. Its really fizzled the excitement of new toys.
