Put in a new battery. I had same problem.Sent to Icom and was told the board was bad. Soldered in new battery and is fine. Cheap way to do it. May work and may not. Worth the small amt to try and repair.Fixed two others putting in new battery.

I would imagine it might have something to do with water turbulance? Do you have a sensor thats located at the bottom of the boat somewhere? In my grandpas boat, the sensor is at the rear bottom near the hole where you can drain the water, if your going very fast it doesnt work very well, slow or stopped and it works fine. If you have that type of sensor make sure whatever holds it is tight so the sensor cant move around.

either that or you got some funky wiring issue lol

Premature power down.

I suspect that the long run will not affect the performance, and I suspect that extensions are available, check with Lowrance.

We set it up and ran it before installing it on the very top of our new boat. It was running fine for a day or two. Then the next time we turned it on we got a error code 6. What does it mean, and how do...

I would get on the Mfg. website, customer service dept. and tell them the problem. They are usually very helpful and you may be able to download a solution on a laptop, wireless computer, then take it to your boat and upload into the GPS. It's worth a shot.

Icom gp 270 ml powers up. No satellite reception

You will almost certainly find that the internal battery has died. So the machine cannot store the time where you are so it cannot find satelllites unless you wait a very long time. You can prove this by looking for a stored waypoint. If all your waypoints have gone, then this is the problem. In my experience the batteries only last about 4 years.

M402 didnt receive the gps signal transmitted by garmin 72 via nmea 2.0

Check the wiring again. Installing my M422 needed to switch the polarity of the NEMA input from my GPS75. May be similar problem

My gps saids i am always in new york even though iam in maryland never moves from new york

If it is constantly on a singloe map location and never cuts in to navigate thjen suspect that
1) the antenna is afunctional, disconnected, or not working to lock onto satellites.

2) The chip that locates and communicates with the satellites is dead.

If it always shows a particular location when started, but does navigate to where you ask it to take you, but always returns to the base location when tuened off and then on. The program in your home address or in SETUP program your location and time zone to have it always start in Maryland.

ICOM GP-360ML GPS Receiver

I had this problem about a year ago. If all you need is the firmware update they will update it at no charge and they told me if it needs repairs they most likely will not have the parts becaus it is a discontinued model. They also said they did checked it and found no other problems. Sent it in to Icom:
Icom America
2380 116th Ave NE
Bellevue WA 98004
They did the firmware update and sent it back to me free of charge. It works great now and my chart cards work great.
