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

• I would think not as the resistance and transponder are matched to the unit.

Here is the link to the owners manual.It has a copy of a wiring diagram.Not sure if it is the one you are looking for but maybe someone else may be able to use it if not. Hope this helps you with your project
Good Luck

Hold down the on button until the screen goes black. wait two min, then turn it back on. If that doesn't work, try connecting your device to your computer and go online to the manufacture website. Most have a way to check your device and fix/update it.

my camera is saying protected memory card and i need help fixing it. i can't do anything with the camera besides look at the pictures on the card. i can't take pictures or access the menu features.

I installed my Navman 4150 depth finder along with the Navman GPS unit when I purchased my Bayliner Trophy 20Ft. Offshore model. Everything was ok for one year and it has been downhill since then. Losing signal, unbelievable high depth ranges, blank periods, etc.. I now can't even get a reading tieded up at the dock. I am now giving up and shoping for a quality unit.. Cape Disappointment.........

I finally got an email reply from Navman. If the unit is less than two years old (mine is not) they will repair it. If it is over two years old, or if you can't prove that it is less than two years old, you can ship it to them and they will repair it for the low, low price of 355 US dollars.

Pretty nice of them since it appears these units are highly problematic isn't it? I am wondering if they guarantee their fix, or just have you on the hook for another 355 dollars later.

Good Luck Everyone,

Walt
