My chart plotter won't display any info regarding speed or direction etc and when you press the 'find ship' button a message comes up with 'No location data' or similar.
It has a card in the slot which is for the right area.

Any ideas whats wrong and what I may need to replace?

Again thanks in advance to all you experts out there :cool:
 
It sounds like it is not locating the satellites to triangulate a fix. Does it have a built-in aerial or a remote one? If remote, is the connection ok?
 
Most likely a simple loose wire on a NMEA connection from the GPS or antenna. You can go into the menu and ask for a GPS fix, any other instruments using the same GPS feed?

It's possible that the button battery in your gps aerial ( mushroom ) needs replacing. This usually happens when the aerial is 8 to 10 yrs old.

Don't ask me how I know this!!!

We used to have one of these. It's either a pulled or loose NMEA cable between the GPS antenna (which is the actual GPS receiver) and the back of the RL80CRC, or the GPS antenna has failed. Twice for us it was cables. Engineers installing new kit through the radar arch had stretched some existing cables.
 
RL80 or RL70 like mine.

If your system is getting on a bit it could well be the GPS ant.The easy option is simply to buy a new Raymarine GPS ant(little white dome thingy somewhere on roof)
Real tightwads will try cutting open the dome and replacing the internal button cell battery poss a 2030 3V. You will need a Dremel drill with grinder and soldering iron plus a real desire to save 90.00.
When this does NOT work and anyway you have practically destroyed aerial in your attempts to open it,you will then try to find a cheaper alternative to the 250.00 that Raymarine demand for new unit.
A certain forumite (no names ) then searched Ebay for a cheap replacement knock off( 89.95) which worked perfectly the first time he connected to end of exisiting wiring to avoid having to dismantle half the boat to run new cable to miles away junction box.
Worth also a look at the Raymarine Technical Forum.

Andy - the Evermore unit looks nice but the ones I can see on ebay are USB connected - are there ones that would connect to the plotter or do you have to switch to PC based plotting? Also are they the same size as the old Raymarine 120 - so they would fit in the moulded recess in the deck?

Its the smaller one of the two .

Just had the same problem and managed to find a new (yes new!) Raystar 125 on ebay (I paid an embarrassing amount for it!!) to replace my Raystar 120
I think the Evermore units are NMEA only and not Seatalk. You can easily set up your Plotter for NMEA but I'm not sure you will get a SOG reading on your 'speedo'
If you have surgeon qualities you can replace the battery.

If I need to buy this unit do the wires have to be run back to the plotter on the dash or can they be spliced in locally to the GPS unit?
I'm just wondering if it's relatively easy or going to be a pig!

I don't see why you couldn't just splice it in Andy , but I would connect it up and test before I cut the cable .

Yes you an still have SOG reading. The 120 was had to be bought as seatalk or nmea and the 125 does both, it just depends how you connect it up.

The op needs to find which one is fitted first as the 120 doesn't have lights on it, does speed show on any of the instruments? Check the GPS status page from the main menu.
It's easy to see how if its wired seatalk or nmea from the connections, these setups are quite easy to find your way around. I have a spare one of each I use for testing.

Also if replacing with new 130 you will need a stng to st1 converter, part no. E22158
