    New boat, new Garmin 4208 gps/map in SET UP intializing, Position Format? it lists 7 choices I have no idea what any of the choices mean, which one do I choose. Do you have to install the SW Update before initial set up? I had it installed at the boat dealer so I have to assume it was wired correctly. Any sugestions???

Same problem here. The 4208 appears to have an over-heating issue that turns off the NMEA 2000 network which contains the GPS 17 antenna. Cooling the heat fins on the back of the unit turns the network back on, suggesting a design flaw.

The question now is to determine WHY the unit over-heats.

Make sure all three T-connectors are connected and that you connect the YELLOW cable to the last one. This yellow cable will need to be connected to power. Then you will get GPS link up.

How to disassemle garmin 4208


If you have the correct soldering equipment and have the replacement part, it shouldn't be too hard. You'll need a jewelers screw driver to get the small screws out. Use a guitar pick to pop open the case. Work it around the case until the back half separates. Clicking and popping sounds are normal. Take out the battery wires. Do NOT yank on the wires... gently grab the plug and wiggle it loose.Remove the screws holding the board to the case to expose the solder side and remove the broken power jack.

Garmin GPS - stuck , not updating, no signal problems, update maps


If your Garmin GPS is stuck on a loading screen, not updating properly, not acquiring a signal or having other quirky problems. You can follow the steps below to help resolve some of these issues.

In order to update the firmware on your Garmin GPS device you will need a USB cable and Garmin's WebUpdater software. You can find the update software from the following link below,

Click here for update software

Click here for map updates

To update your firmware through the WebUpdater software, you want to turn off your GPS device, plug it into your computer. Run the WebUpdater software then turn on your device. If the software does not list your GPS then click the "Find Device" button.

Updating the maps can resolve issues with missing streets, or the unit being off entirely(roads are updated throughout the world on a constant basis). Keeping your software up to date is always recommended.

Firmware upgrades will help resolve issues in the operating software, and may even help GPS problems you are experiencing. If not, you can perform a soft reset. As a last resort, you will want to perform a hard reset below.

Perform a hard/soft reset
A hard reset will reset the device back to factory defaults. This will also delete any of your personal favorites saved on the device.

Soft Reset

Slide the power button to the left and hold in this position for 8 seconds. Push the switch to the right to power the GPS back on.


Hard Reset
Turn the unit off. Press and hold the bottom right of the GPS screen. Continue to hold while powering on the GPS. you should now have a prompt asking you to erase all data. Select Yes. Afterwards, it is recommended that you leave the GPS outside somewhere safe to acquire a GPS signal. Once this is done, you can update the GPS using the update steps described at the beginning of this article.

Hi, my Garmin 3010c is 40m off true position. I hav another plotter (not Garmin) an it't on the spot. It7s not the problem with poor signal. It has signal form 6 or more satelites but it is allways...


Hello,

There are too many variables that will affect the GPS to determine if the Garmin is off or the other plotter.
The only way to verify the GPS is through controlled simulation or using waypoint averaging and survey benchmarks to confirm the location.

Garmin Nuvi 205 Problems aquiring stellite


usually gps are automatically sensing the signal, with clear view without and sometime even with minimal obstruction like trees windows etc. there is no other way your gps could not acquire signal unles it is having a problem .

all gps thesedays have 10-20 meter accuracy, it is only a receiver, this model particularly have the highest signal.

in other words i suggest you reset your unit from the bottom and see if there is any improvement, replace the unit

cheers

No guage screen on my garmin 4208


Need more info:

Is your Garmin hooked up to your engine's computer via an NMEA 2000 data cable?

The gauge option will not appear in the menu if the GPS does not recognise the data coming from your engine. (If you turn on the GPS simulator, you should see the gauges on that screen.)

There are 3 possible reasons that the gauges do not appear in the menu:

1) improper wiring between engine and gauges.

2) GPS has not been set up to receive data in the GPS's NMEA setup menu.

3) Engine has not been set up to send NMEA data.

This is a relatively new feature that only works on newer engines that are NMEA 2000 capable, such as Volvo and Evinrude Etec.  The engines usually need an optional instrument package to make use of the NMEA 2000 system.

We're just scratching the surface here, please reply with any questions.
