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.

I suggest you try resetting the device by following the instructions in the owner's manual. If the issue persists, it may be due to an error in the map database. You can try reinstalling the maps to the memory card after unlocking them for your device. If you are still experiencing issues, please contact Garmin Product Support for further assistance .

By 'resetting' you mean it switches off, and because it is connected to power, it boots back up. Do you have a SD Card in it? I had trouble with a Nuvi 1350 with SD Card that had the whole USA Map on it, mine came with the Canada Map only. It would randomly turn off, so I decided to buy a Factory Refurbished Drive 50. I removed the SD Card and Reset the Nuvi and it worked perfectly after that. The Drive 50 was also a bit flaky, and resetting fixed that as well. You can back up your Favourites beforehand.

I recently purchased a Garmin GPSMAP 78s I had a lot of trouble calibrating the compass; I literally tried it hundreds of times without success. I also did a hard reset etc etc. Believe me I definitely tried everything possible but to no avail I did contact Garmin but they didn't have an answer straight away for the problem I have now sorted it as follows: Do each step VERY SLOWLY, MUCH slower than you think you should There are three steps to go through in calibrating the compass 1)Spinning the whole unit around flat 2)Flipping it over longitudinally and then 3) Flipping it over end to end. But remember do each step VERY slowly and go to the next step when prompted by the unit This solved my issue. I can now calibrate my compass 9 out of 10 attempts Hope that helps

To open the MTP settings on your Garmin Nuvi 50LM, you will need to access the device's menu. From the main menu, select the "Settings" option and then select the "System" option. From there, you should be able to access the MTP settings. If you are still unable to access the settings, you may need to contact the manufacturer for assistance.

You will need to go to the Garmin website on your computer or laptop and set up an account. I think the sign up is free. You will then need to connect your Garmin to the computer and update it that way.

Hi Earl, Sometime it could just be of aging. I have a 130, it was having similar problems, until i realized it was the screen not showing, but power on turning on. In your case, I probably probably try a hard factory reset as follows: To perform a master reset:

1. Turn off the device.
2. Press the PAGE, ENTER2, and POWER buttons simultaneously.
3. Release all buttons once the Do you really want to erase all user data? message appears.
4. Select Yes.

hope this helps! Kevin

It appears to be a known issue. You can try some Electrical Switch and Contact Cleaner in the first instance. This NOT WD40. https://www.google.com/search?q=Garmin+etrex+10+click+stick+problem ..
