I have a Simrad NSS evo3 that has no audio source. It is connected to a INFINITY MBB400 NMEA 2000 BLACK BOX but after a firmware update on the evo3 it won't connect to an audio source.

Question edited for clarity.
Question moved from Computers and Internet.

Check out the first two links

I did a search and found this as I don't own one not sure if this forum will help or not but thought I'd pass it on anyway.
Best to you.

Nokia 6300 firmware update
Subject: how to update firmware for Nokia 6300 to the latest official version
I bought Nokia 6300b RM-222 with firmware version 4.71, but now the latest firmware is 7.30 (or any latter build). But Nokia Software Updater (link) told me that I already had latest firmware and refused to update my phone. Below I described the steps to upgrade Nokia 6300b RM-222 from version 4.71 (or any other version) to version 7.21/7.30 (or any latter build).

Get someone from a marine electronics company to do this for you. If you are unsure of the basics of what you need and you attempt to do this while going in blind, you may ruin your nmea ports on your navnet and autopilot. While I understand that you are trying to save $$$ by doing this, there's more to it than just wiring. There are port setups and nmea sentences to enable etc.

Yes, the NMEA- output (I think you lefy uot the "-" in your questoin), anyway, the NMEA - or NMEA negative or NMEA ref is hooked to battery supply ground.
Dont forget to program the Garmin to look for 48,000 baud data.

if you haven't upgraded to the latest firmware , you can use NSS to change the product code
to use NSS go to
http://senseapplied.com/index.php/how-to-use-nss/
for product code you can use
0576447: E63-1 RM-437 Country Variant United Kingdom GB CU Blue
0576446: E63-1 RM-437 Country Variant United Kingdom GB v1 Red
0586830: E63-1 RM-437 O2 Ireland IE Black O2_COLOR

after changing the product code , reinstall the firmware via Nokia Software updater and you will be all set

Your plotter can talk to you Radio and your pilot. It sounds like one of two things.You must go into the system setup menu and turn on the nmea sentances. You will need to turn on RMB, RMC, GGl at least. You can turn on all the sentances if you like it does not matter. If this does not fix, check color of wiring is correct. Remember you have to go from NMEA + out (on plotter) to NMEA + IN on Radio.Then you need NMEA - out(on Plotter) to NMEA - IN on Radio.
You can look at the sentances wirth a multi meter coming out of your plotter. You put meter in DCV and connect across the NMEA out lines. You will see the meter move every second or so as it send a sentance.
