To get back up and running you are going to have to reset the unit. This is from the handbook:

Note: Take care - factory reset clears allWaypoint and Route databases.
➤ To perform a factory reset:
1. Power off the unit.
2. Press and hold CLEARwhilst powering up until <Erase backup procedure>
is displayed.
3. Either press CLEAR to abort Factory Reset and resume normal
Power-Up or press ENTER to continue Factory Reset.
4. Press ENTER again; the unit restarts as for a first time PowerUpwith
all values reset to their original factory settings

When you hit port and have an internet connection, make sure you are running the latest software version, currently listed online as version 1.09. You can download it here:

I've had the same problem. before replacing the antenna, try to reset the antenna by removing power to the Raystar 120. Disconnect power by either turning off all batteries or disconnecting the red wire from the antenna at the point where it enters the junction box for the chartplotter. This action effectively removes all memory from the antenna and resets it to factory settings. There is a lithianium battery in GPS antenna that holds memory data in the antenna. Disconnecting the power to the antenna for a few seconds clears the memory.

This is exactly what I did and when I turned the chartplotter back on, my Raystar 120 immediately began working again.

SOURCE: I just bought a boat with a Raymarine C80 chart


Your problem is the 4GB card. The Raymarine C-Series have a problem with their compatability tool and larger CF cards. You should use a card no bigger than 256mb.

The card probably worked in the store because the newer models accept larger cards.

Get an older card from ebay etc and copy your 4gb files onto it and try again. There is more info here:*&p_li=&p_topview=1

Hope that helps you out.

SOURCE: I removed the Navionics card

Here is a link to the main RAYMARINE support page for that model:

If there is no physical damage to the card or the card reader on the unit, then you can always try a master reset procedure and see if that will clear your problem.

To master reset a C120, have the unit off, press the first soft key next to the power button and hold it. Press power button (while keeping the soft key pressed). You will get a message stating that it will reset, followed by a countdown (keep pressing on the soft key). Once beeping is done, release the soft key.
Please comment back here to this page if you have any details to add, have any questions, have difficulty accessing the links, or just require further general assistance and I will respond as soon as I see it.

I hope that was helpful to you, good luck.

Hi, check if the card reader is OK , the slot must have good contact with the card, if there is bad contact it will not work.

Garmin GPS GSMAP 182C Chartplotter will not boot up

If the unit doesn't go further from the reading card. this may indicate that theres a problem in the memory card.

Not being able to a get a signal lock on satellites would indicate a problem either in the software something is wrong or not geting loaded correctly (the memory card) Or a hardware problem.

You may have to take it in for service if you are unable to check the memory card or replace it.

I have a 276C and have a marine charts card in it for navigation. When I have the GPS hooked up to my lap-top, it there a way to view the marine chart on my lap-top screen? I would think this would be a...


You require a chart navigation or free viewer program on your laptop to decipher the information your GPS sends and to interface with it.

There are a few of these programs available, but we opted to purchase CAPN Voyager (The CAPN) many years ago and have been quite happy with it for the 16,000 miles of coastal cruising we've done. The program allows us to see our progress in real time on the computer screen and is easy to use

Prior to that, we used Maptech's free chart viewer which allowed me to plan routes and then put the lat/lons into the GPS unit, but had no interface with the GPS to allow us to navigate in real time.

Hope this helps.

I just received a model #441 S from West Marine. My boat is moored in Alburgh, Vermont USA. It's about 1 miles south of the Canadian border. The unit won't show any chart untill about 2-3 miles south of...

You will need to get the Canadian Bluechart Card also. At this time Garmin doesn't pre-load the units with Canadian Charts. Maybe in the future. Here is a link to the card you will need.

Hi,when i switch on my lms-332c the map does not come up on the screen.If I remove and replace the map card it works perfectly. Can I fix this? regards nigel

I am guessing that the card you are using is a NAVIONICS chart? There have been some Lowrance units that were made around the same time that have had problems recognizing a Navionics chart right from power up.

Make sure the LMS-332 has the latest firmware version which can be downloaded from

If the update doesn't help, this is going to be a compatibility problem with the LMS-332 and that particular card. You will need to replace the card or upgrade to a newer unit...but probably can just get used to removing and replacing the card when you turn the unit on.

Lowrance not reading navionic

Make sure that the 5200c is set to read the Navionic card. You can set that under Map Data.

Gpsmap 182c

My 182C developed the same problem. It appears to be a problem with reading data from the card. When I power up the unit, sometimes it will display "Reading Card" for a long time and no data will be read. I've found that if I open the latch and push in on the card as I press the power button, it will only then display the number of maps loaded. Sometimes less than other times. Most times a lot of data is not loaded from the card causing the problem frankcps describes and other problems, such as no data for tide stations, anchorage, etc. I tried cleaning the contacts on the data card & where it plugs in, but still continue to have the problem.

Garmin nuvii 350-anyway to install marine charts on this unit?

No. This unit is not designed for marine use, and therefore is not designed to accept marine charts.
