hey guys I just bought a new hummingbird 858c hd had it installed by a marina that has done all the work on the boat great place and we went out to the lake last weekend everything worked great....except the sonar wont work and the depth readout will not show up it is just a blank spot the black box wont even show up. We took it back to the marina thinking it was in the wiring. The owner saw what it was doing and had another head unit he plugged it and it worked so I returned just my unit for another one today and what do ya know the same thing happened......Im at a loss and im not sure what to do here any help anyone??

Thanks ALOT

Maybe transducer? You're getting the same results with 2 head units... chances of 2 bad head units is pretty slim.

was the swap unit that worked the exact same as yours. you may want to check the plug for any movement. and did you lake test the other unit.

[trail11591]

that is what I am thinking to but I cant explain why the other worked? just powered it back on thinking maybe it wasn't getting enough power the display showed 11.6 volts

i think his had down imaging mine does not have it. No movement in the plug made sure it was all tight i didn't take it back to the lake i figured it should at least register something for depth i didn't put the transducer in a bucket of water if that did anything idk

Try resetting back to factory settings, we had an issue with ours not showing one of the frequencies and resetting fixed it. If that doesn't work I would give Humminbird a call.

[trail11591]

I reset both of the units and when I talked to hummi bird last time the lady also thought it was the unit I think I'm gonna try to get my hands on another transducer at this point

[sjk984]

Try a hard reboot. You'll have to go online to see how to do it. If not call bird great CS. Just be patient

Crazy Yankee is a rep for them I thought. Drop him a pm.

Tomorrow I'm gonna swap transducers and hope that will fix it

[Fishjay]

Yes it's the transducer had problem like that myself after a year never heard out of box but who knows. Whomever you bought it from should swap out at no charg to you. They will send back as defective at least that's how I got my new one

[trail11591]

Yep d and r in kzoo is swapping it tomorrow for me hope this itls it I just thought it was strange the other unit with down imaging had something of a sonar come on but not the others

[Yankee Troller]

My $.02 says it's the ducer also. Keep us informed on what happens when you swap that out.

[trail11591]

Got home earlier that I thought last Nite swapped it out and it seemed to work heading to the lake tonight after work to really test it
