Nmea

[Hightower]

Anyone connected the NMEA from a Silva S10 to a Garmin 182c. The instructions are less that helpful and I don't really want to damage the units before I use them.

Connect the red wire from the plug on the back of the S10 to wire marked as NMEA out TX on the 182. blue for com1 or green for com 2, doesn't matter which one as long as you enable the NMEA output in the menu. You don't need to connect anything else as the screen and return are connected through the negative on the radio.
The instructions for the S10 are not very clear as you say

Thank you Mr Bear.

The instructions aren't that clear, are they!

What do you do with the negative from the radio? Am I right that you said in your post, not to use it?

I have a Nmea Out on my Navman fishfinder also, it has a speed transducer. What do you think the deal is with this? Do you think I can connect this as well?

Any comments welcome,

Andy

You have two NMEA inputs/outputs on your 182 but should get away with using just one. Connect the fishfinder Tx wire to the brown (Rx) wire coming out the 182.
This leave you NMEA Ch2 on your 182 for anything else you may wish to fit in the future.
The wires connected from the radio are +red and -black to the battery (12v) and the red wire from the small plug connected to the nmea output from your 182 as described above. the small black/screen wire from the plug on your radio does not need to be connected.

Excellent!!! Thanks very much for taking the time to put me right. I'll do the wiring at the weekend.
