Adapt 997c si gps to navnet furuno sounder

That is a Furuno 1823C Radar -000-138-972 (10 meter Radar cable) $150.00 msrp from Furuno. Give their Camas Office a call or your nearest dealership. The Furuno number in Camas, Wa 888-834-9330

n the system setup, under “UNITS” I set BEARING to “MAG” (magnetic). This will cause the unit to display course / bearing information in relation to the Magnetic North and match magnetic compass readings. It is not the same as True North! One has to be careful with this setting. There are a number of areas where the earth's magnetic field is locally disturbed, sometimes very significantly. Your GPS may not account for it. - again, under “UNITS” I set “METRIC”.

If you just have the transducer and no network sounder youre pretty much dead in the water. along with your transducer, you will need either a BBFF1 or DFF1 sounder. Since they operate on a network they will have to be configured depending on your setup.

You must have a heading sensor input for radar/chart overlay. (i.e. PG500)

vorrei se e' possibile avere il manuale in irtaliano del radar furuno 1621,grazie

If it has a round radar plug in the back then the answer is yes and it already has radar support. However to upgrade your unit to the latest software you will need a dealer for that. It's a very tricky process and if not done properly, you can ruin the bootloader programming that starts the unit. I know of a dealer that does this if you want to check in with them. You can even send them the unit. Try www.mid-shore-electronics.com.

Reinstall the operating software. The unit should probably go to Furuno.
Try operating it with only a GPS connected (no radar, no network). If this resolves it, it is almost certainly software. It could be low voltage or failing mother board.

Remove all connectors aside from the power cable then attempt to power up. If the unit turns on, it may be your radar if you had one one it originally. If so plug the radar cable back into it with it off and try powering up. If it does not, then thats the issue. the Radar or your cable.

If the AIS targets are out compared with radar target then turn compass to superimpose radar on to AIS.
If the AIS info is out compared with chart then suspect GPS. This could be yours or theirs depending on how many targets are out and whether it consistantly in one direction.
Good luck
