    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.

Why doesn't the GPS pick up a current GPS signal?


You may need to do it outdoors; a building may interrupt enough satellite signal that it (the GPS) won't lock to it (the signal).

If it always says "GPS SIGNAL NOT DETECTED" when it's outdoors, I don't think you're going to get it to ever work. It may have been dropped & the internal antenna damaged.

Gps singal lost


Often, when your GPS is in a "covered" area ... e.g. inside a building, in a tunnel, under a bridge, amongst / under tall buildings, etc... when there is no open space (directly) between your GPS and the satellites, your GPS will loose its satellite signals. If you're in such locations, try to find some "open space" and wait a bit for the signals to be picked up again.
Another common reason why the GPS doesn't get signals, or doesn't get the signals quickly, is because the "latest" satellite positions (locations) have not been updated in your GPS. If/when you connect your GPS to your computer (e.g. using HOME ) and download the GPS satellite (QuickFix) location information, your GPS will have the most recent locations of the satellites in your vicinity/region. With this information, your GPS can pick up the signals more quickly ... instead of having to search/scan around to find the signals ... which can take a bit more time. While your GPS is searching for the satellite signals, it shows the "signal lost" or "no GPS signal" message.

Does not pick up satellite signals


The gps device is not receiving signal simply because the strength to receive signal is weak. What you have to do is to reset the gps device by holding the power button for about 15 seconds or there about, then you release it when the gps restarts. It will acquire signal after resetting the device.If it does not acquire satellite signal. You can also try to use the gps in an open space where the gps will be facing the sky, if it does not, then you replace the antenna of the gps device.

Hope this information helped.

No longer receives GPS signal


Does this unit have an input for an external antenna? If you get/borrow another antenna you could see if it starts working. That might isolate the problem to the antenna.

Can't get a GPS signal for last 24 hrs


I had a similar problem and did solve it with the soft reset (pressing reset button). I have a One XL and there is a small reset button that you push with a paper clip. On the XL 330 you press and hold the on/off button for 15 seconds and the unit should reset.

My symptoms: Would not find a GPS signal. When I looked at the GPS Satellite status (press on the GPS signal strength bars, again on the GPS/battery status) you can see it locking on up to 8 satellites but would still not show a gps signal lock. Normally it only takes 4 satellites to get a gps lock. My other sympton was that when I attached the GPS unit to the computer and operated it with TomTom Home, it worked fine and locked on to the gps signal quickly (even inside my home). But it would never (at least for 30 minute trips) lock on to a gps signal. After doing a reset it began working normally and locked on to a gps signal after finding 4 or more satellite signals.

Waiting for valid gps signal


The GPS needs at least 3 satellite signals to operate.You are probably in a bad reception area. Move around a bit and try again until you see a signal array of 3 or more!
