Software where can i find a software to plot my marine waipoints, and my marine charts in my card, my gps furuno?may i use NAZARETH ? I WILL HAVE THE SAME ANSWER?

Try changing range setting. Also try reseating the chart card if you're not using the built-in NOAA charts.

The battery is soldered and glued into the unit.The battery is a CR2450-3 volt lithium battery and apparently, easily found at radio shack for 7 bucks.

Time and date data is transmitted from the GPS satellites. It's only necessary to set the UTC offset for your area, 12/24 time format, and date format preferred. These settings are in the general menu of your unit.

If it does not have a usb port then you need to have a sd card reader on your pc and use that to transfer data

No it does not output any type of radar video data.

Make sure your time offset is correct and also make sure you have not accidentally offset the chart. Also keep in mind that there are places in the charts that you can overzoom which can also cause this problem.

Turbulence on the transducer is almost certain. If transom mounted, **** it slightly deeper aft and ensure that the leading edge is not exposed. If through hull, call me 847-746-0100

Furuno just stopped producing these models about a year ago. They use a special chart card. You can still purchase the cards from Navionics or C-map if you need to. I will tell you from experience that you should get your internal battery changed out if you havent done so already to keep from losing your settings and waypoints. The dealer will have to save them for you though and put them back on. Furuno made a GP7000 to replace this one and it's uses SDcards and is nothing like the rest of Furuno's product line. The best replacement for this unit is the Garmin GPSMAP 700 series. You can use your old furuno transducer if you have one (with an adapter plug). This garmin unit also has a built in GPS or you can use an external one. The 700 series will be shipped in April. Check out Garmin's website or mid-shore electronics.
