Internal GPS antenna won't turn off

As soon as the unit is powered on the GPS turns on regardless of antenna position. Is there a way to turn off the GPS on the circuit board. I cannot turn it off using the screen because it is stuck in an on / off loop at power up...which I found out how to resolve but can't with the GPS on. I have opened the unit removed the circuit board and removed the single wire connecting to the flip up antenna and that does not turn off the GPS. What am I missing?

I had the same problem. I pried open the antenna cover about half an inch. Tapped the dislodged magnet out. The quarter inch magnet is fitted into a small oval rubber piece with two small holes one at each end. The rubber piece and the magnet can be reposition back to the two pins close to the edge of the antenna cover.

There is a small round magnet inside the antenna cover which is used by the unit to tell the CPU if the antenna is raised or not.

Most likely you dislodged the magnet when you dropped it. When the antenna is closed the magnet will close the circuit.

This is similar to using those magnetic contact for home windows in a burglar alarm system

    The magnet is less than 1/8" in dia. Buy one of those very small refigerator magnet, that people use to stick notes to the refrigerator. Hold the magnet near the back of the 3600 in the antenna recess and see if you can get the GPS to turn off.

    To take apart the antenna will require taking the entire garmin apart. The spring loaded mechanism that holds the antenna to the main body is located behind the main motherboard.

    Thanks audiqv8 that makes sense. Any ideas on how to fix the problem?

  • Ralph C Jan 28, 2008

    Thanks audiqv8 for those details. Magnet won't turn gps off. I will disassemble and investigate further. Like I said earlier, everything still works great except that gps is always on so when not in charging cradle battery drain is greater. Don't want to mess things up so I will live with gps always on if necessary!

Why when i plug in my garmin device does it show a computer but no maps

Are you using a simple USB lead plugged into a USB power source? If so, the unit is (correctly) going into its USB mode.

You can also try different USB leads, some do not have the data line so act as just a power lead. It's the data line that signals the GPS unit to go into USB mode.

Regardless of the type of lead, your unit will charge like this and then, when the lead is disconnect and the unit turned on, will work normally off the internal battery.

If this is your experience, you will need either the correct GPS power source or a "USB power" lead.

Sounds like an antenna problem. Some units have internal antennas and some have external ones that plug into the unit with a small cable. The unit thinks you are still inside and cannot find a satellite to lock on to.

Locks up after a few seconds/have to kill power to reset

This may help. Mine has the GPS antenna build into the bracket at the back. I removed the bracket and the unit did not go into the error screen and the sounder worked fine. The GPS would not locate but it has not antenna attached so DOH!! I have orderd a new antenna with the BNC connector and will post if that fixes the problem. At this point I'm guessing its a blow GPS antenna.

had same problem with lms337. i had upgraded the unit but had not upgraded the lms2000 gps module. i was turning the isolator on in the boat which powers up gps module, if the lms337 is not powered up as well the gps unit goes to sleep. the upgrade fixes it by checking that the unit has not been turned on periodically. otherwise as soon as you power up gps module also turn on lms337. lowrance product support sorted this for me.

Fritzed Unit when antenna up

I have a similar problem but I can't turn the GPS off at all, even when the antenna is down. As far as the power on/off cycle, I found another link on this site that said to turn off WAAS while the GPS is off then when you turn it on the unit will not power cycle continuously. You loose the WAAS feature but the GPS and unit still works.

No signal

Remove the Antenna while in the upright position, clean connection and replace. Set the GPS current position. Then initialize the GPS. Select Yes and leave the unit alone for 20 minutes. Do not press anything else. The initialization runs in the background. make sure you have a clean line of sight to the sky. Then turn the unit off and back on. You should be OK.
