SOURCE: No power

Could be worth a look at the connector on the back of the unit itself. As I discovered a few weeks back, they aren't as saltwater resistant as the IP67 rating would lead you to expect. Compare the pins in the plug with the diagram on page 99 of your manual (also downloadable from http://www8.garmin.com/manuals/GPSMAP198CSounder_OwnersManual.pdf) and make sure all the pins that are supposed to be there actually are. In particular, make sure pin 15 is in a decent state. This one carries power to the unit, but will act as a sacrificial anode in the presence of saltwater, and can rapidly corrode to oblivion. If this is what has happened, you have a bit of a problem, because Garmin, don't appear to be very good at making spares available. I was lucky in that the GPS I was fixing was a lower end model that only used five of the seven pins in its connector, so I was able to rewire to provide a supply through the unused pins. The diagram suggests that the 198C also sports a few unused pins, so you may well be in luck. A.

SOURCE: no sound whatsoever on GPS

Maybe you have turned the FM modle on, which means the sound can only comes out from your stereo system.

SOURCE: GPS was working fine. Stopped and turned off car....

A Garmin Nuvi 1300 that won't start, freezes on 'loading maps,' or is acting erratically is symptomatic of having corrupt firmware.

To correct this, I recommend backing up your favorites, clearing all user data, and if it still is stuck, then updating your Nuvi firmware.

Follow these three steps to take to get your Garmin Nuvi 1300 running like new:

  1. Back up your Favorites.
  2. Perform a Hard Reset.
  3. Download and then run Garmin WebUpdater to replace its firmware / system software.

I hope that helps.

SOURCE: 310 c garmin gps on boat not working

The red question mark indicates a failure to communicate with a locating satellite. If you are transiting or in an area where you know you have adequate coverage the likely problem is in the wiring and connections between your GPS antenna and the 310c head unit itself. A common problem is the connector bus itself on the back of your screen. Often it is exposed to salt water and humid conditions and the terminals corrode. I use a dielectric grease and fill the female connector pin holes to aviod this and ensure good connectivity. Another quick test is to reboot your head unit by powering off and back on. Its possible you are merely dropping signal and the unit needs to reaquire the broadcast. If you still have no joy its time to take it to the marine electronics tech and get it looked at. Garmin is making some great new products and it might just be time to upgrade anyways! Best of luck.

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.

My boat is pointed in the wrong direction on my Raymarine C80 chartplotter?


I'm not sure where you would locate "reset to factory specifications". Look for it in the GPS menus (may be in the System) and reset, it is no big deal to reset a GPS, it will not hurt anything. I the GPS is set to back Track. To check this turn your boat around and follow the track on the lake chart. If you and your boat are now going in the same direction the GPS was set on Back Track.

My son and his buddy recently installed an amphlified stereo system on our center console and there is something strange going on that I can't figure out. It is a Clarion stereo with a JBL amp. The boat...


If a boat is anything like a car, the amp's negative post should not be connected to the battery, but to the ground of the boat. In a car, the entire chassis is grounded to the negative terminal, so when you run a line from the positive terminal of the battery to the positive post on the amp, and a line from the negative post on the amp to the chassis it is a complete circuit. I highly recommend placing a fuse on the positive line from the battery to the amp. Wiring this way prevents the amp from blowing up your battery, as well as prevents the battery from blowing your amp. Hope it works.

I think the transducer is down too low. Raise it up so that the center of it is in line with the bottom of the boat.

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.

This is a common problem if the GPS is hooked up to an electronic heading sensor such as an autopilot. If the heading sensor is not calibrated properly, the boat will appear to be facing the wrong direction.

If you have an autopilot, consult the installation guide and perform the sea trial procedures. That should get your boat lined up properly.

GPS screen went blank


My problem exactly. Unit would start up, acquire satellites, then the screen would go blank with a single vertical line. Unit would not respond to buttons or even turn off. Unit works fine after I did the reset:

- w/unit OFF, press and hold QUIT+DOWN+MENU
- press and release the power button, release DOWN, keep holding QUIT+MENU for 5 seconds.
- unit prompts something like: "erase all data;" choose yes.
- you will lose waypoints, etc.

Go to the Garmin support area for details.
