Happy Healthy New Year to all Our C-Brats
We went out and spent New years Eve at our Club's Island camp Great Fun but My 498 Garmin (06) model) gave up the GPS function No speed , no position .Is this usually an antenna issue ? I'm thinking of taking my GPS and try it on friend's boats ?

Also my type 800 Wallas gave up the Ghost It makes noise like it's pumping fuel but no red light ignition You can smell K1 fuel but no Cigar?

Any thoughts Buy new GPS and use Wallas as anchor ?or call Scan marine and buy new Antenna?
 
As Brent says--check the voltage, with a volt meter (should be in the tool kit of all boats).

If you smell fuel, check all of the fittings for tightness. It sounds like either sucking air, or fuel leak. These are easy, and cheap fixes. Scan Marine is expensive (but good). Always try the simple DX and RX first.

As above, make certain 12v is available to each device. Try a different ant. or check the coax cable / connector between ant. & gps :mrgreen: :thup
 
For me if I were in your shoes I would update the Wallas and get a new Garmin unit. Both items seen many improvements. No sense throwing good money after bad. JMHO

The Garmin GPSMAP 498 is a GPS receiver and chartplotter. Is this what we're talking about? If so they still are for sale, new at ~$650. And, yes for around $700 you have a wide variety of 7" chart displays with a built-in GPS; from Garmin, Lowrance, etc.

But here's another thought. One can buy a laptop ($400-$550) that will run OpenCpn (free) which uses NOAA charts (free, and the basis for Garmin, Jeppson, etc. propitiatory charts,), buy a USGlobalSat GPS puck ($50). AIS can be added for the cost of a receiver ($150.)

For less than a dedicated 7" display, one can have a 15" display with a great charting system. You can add radar (Garmin or Lowrance.) OpenCpn is constantly updated with optional "plug-ins." I've used it for a couple of years and it works as well, even better, than the commercial systems (Fugawi, for example,) because it's developed by people that use it.

If you have a PC computer you can download and try the latest version of OpenCpn. Scroll down to version 3.3. This is the version I've used. The GPS puck has a built-in antenna that's worked from Canada to Mexico, so no external antenna is needed.

Thank God for spell check.

One thing I would say is that a chartplotter is probably a lot more robust in a marine environment than the average laptop regarding both the hardware and software. With a laptop, who knows what the next Windows update is going to do to it.

I would use the laptop for a backup or route planning purposes and have a proper chartplotter as my primary navigation device.
 
We have a Garmin 4208 and use it for radar overlay, fuel management, depth, and water temp. We use a 15" laptop with a USB GPS puck fastened with Velcro right inside the copilots front window. We use Coastal Explorer software that gets constant map up dates for the whole coastal U.S. and a built in blog that accepts pictures. You can buy and download additional maps through Coastal Explorer via download. We needed some charts for a Canada trip. We have Windows 7 and we do routing in the planning mode and save routes as individual windows documents. When we are ready to cruise we open the document then switch to the cruise mode and wa la off we go. No internet needed. The routing is so much easier using a mouse to point and click on a 15" screen than using a chart plotter. I steer the boat with a hand held auto pilot and just keep the boats icon on the route line. With the larger screen we can zoom in on things and still have a decent overview of a given area. Plus the software has Active Captain software imbedded so we see it as a complete package. Since we don't want water splashing on anything including the computer we usually run with the slide windows just cracked. No issues. Windows gets updates just like Apple. Say what you want but the laptop w a GPS puck but for us it offers a lot more options than a chart plotter. I like the multi function GPS but for doing routes, navigating, and storing them I have been happy with Coastal Explorer on my laptop for about 4 years now. Big screen heap big better.

I took the 498 to West Marine and asked their advise They said to upgrade firmware and buy a new puck (antenna)
I checked out my Barn and found a brand new puck and box for my 498 so I tried that and then reset my Garmin as per Garmin instructions and my GPS came back to Life . I also asked them to send new firmware they ask for a $50.00 deposit and then when you ship it back you get your $50.00 back. I just saved $700.00 which is good since we are in a major remodel new A/C,Roof,painting inside and out ,driveway ,pool heater , etc , etc ,etc. My wife is happy she just added another $700.00 job to my list .

Now to try to fix the Wallas stove I'll remove fridge and get into the stove maybe send it back for a tuneup to Scan marine I will check all the fittings put in new fuel and hope for the best .
This is another subject upgrading your firmware for Garmin I can do it to a USB stick from my computer but how does one get the USB into the Garmin GPS??

If you have a Garmin card & matching reader you can download for free & install. When you get the $50.00 loaner, take out the map card, insert the up date card, turn on & follow on screen prompts. Have a good one :lol: :thup
 
Based on advice from Garmin techs for this same problem in the same model, on a used 2006 C-Dory; I paid the $50 deposit and got the update card. Fixed the same lack of satellite detection problem you had. It then started having troubles again. Did more research. Found my magnetic compass needed to be more than 12"/1' form the internal GPS antennae. Moved compass - re-updated software. No more problems. Besides the Garmin Card angle mentioned above, Garmin FAQ/support pages allege the update can be downland and synched to the Garmin via laptop. Don't have wi-fi where my boat is stored so couldn't attempt that.
 
You don't need wi fi to sync the computer. Just download the file at home, then transfer the data via card, or sync at the boat from the computer.

The 498 was a good chart plotter/sounder for its day. However, newer units are not that much more (for example you could get the 740 S for a bit over $700 back a few months ago, when the newest xs series came out. The prices seem to have gone back up now--but they will be down again--and the xs--much improved, will also be on sale before too long….progress, I think!)
