    Black is ground,there are 2,use either.Brown is not used.White is NMEA out. Blue is your NAVBUS.negative. Red is power in 10.5-30.5VDC. Orange is NAVBUS+, YELLOW IS AUTO POWER IN Green is external alarm out 30 V DC 200 mA MAX. These are the power cord pin colors.They are in pin order. Pin #1 is at 11 oclock on the fish finder and then runs counter clockwise.Hope you are all set.

    Hello, They give me this answer: I do not have the pin out for the old Navman 4150x. Only the transducers made by Navman would work on Navman products and not other brand of transducer will work. The electrical hardware and software does not allow for another manufacture's transducers to work. Tom Thank you for choosing Navico products!

I have lost all my wires to my Bunker Hill security camera item 95914 how can I make some more

Hi Jeff
It looks like the camera use an RJ 45 Plug to transfer the signal and power to the AV and power plug connectors. All you have to figure out is which pin goes where.
Power uses 2 pins, Video uses 2 pins and Audio Uses 2 Pins.
So you can get a network cable with an RJ45 connector at the end and connect the AV and power plugs on the other end. I just dont know which pins are witch.

I can't see the picture on my navman fishfinder looks like pixcels are gone on the screen. Is there any way of fixing this

Have you checked the transducer for damage, or the wire to it. Also check the connection on the unit itself. On my Humminbird there is a Demo Mode. See if yours has one? If Demo Mode works, then it is the transducer.

Here is the contact page of the company.

Garmin 300c fishfinder will go from correct depth to 0.0 ft while traveling.Have to turn it off and restart. It is on Hurricane deck boat 198. It is located between engine and leveling tabs.

My experience as a user is that turbulence around the transducer can cause mine to flash and the depth to remain static.Is your fault affected by speed? Sounds to me that you have a faulty connection causing the transducer to "not register". I'd check connections and also the integrity of the transducer. Hope that helps...
Best of luck

Just replaced battery but dont know how to reattach ribbon cable on nuvi 200

flip locking flap on connector away from the gold pins. Slide the ribbon cable into the connector on the side with the gold pins as far as it will go. The ribbon goes face down with its gold pins facing down. Then using two fingers flip the locking flap down and toward the ribbon cable. It should click. Be careful, if you snap the flap it is game over.

Connections problem

Question: What are the extra wires used for on the power cable for my fishfinder?
I found this on the carmin website under questions and answers. I think your cable is ok to use according to this.
--> Answer: Not all of the wires in the harness are required for use. To connect the unit to the power source, only the black & red wires are required (black to ground, red to positive). Here are descriptions of the other wires in the harness:
  • The Blue wire is used for a NMEA data out connection to another NMEA compatible device. The fish finder outputs NMEA 0183 version 3.01. The receiving device must be compatible with this format and looking for the NEMA sentences DPT, DBT, MTM, or VHW.
  • The Brown wire is used for a NMEA data in connection to receive data from another NMEA compatible device.
  • The Yellow wire is used to connect to an external buzzer or alarm to alert you to any alarms which have been set to sound on the device. The Yellow GARMIN wire connects to the negative end of the external alarm. The positive return on the alarm will connect to the red positive wire of GARMIN.
  • The green, white, and any other colors present have no connection purpose related to your fishfinder. The 18 Pin connector wiring harness is used by several other devices which utilize these wires.
If the device is only being connected to power & do not require a NMEA interface, PC connection, or external alarm support, only the red & black wires are required.
