sonar interferance with radio help needed?

[mickey1]

We have just wired in a radio only to have interferance from the sonar, is there anything we do, or buy to stop this, the sonar is a hummingbird wide, and the radio is ICOM M59 VHF
we have all the wiring in the same section, would it help if we seperated the sonar wiring from the radio wiring?
We always come here for help as you guys haven't yet let us down.
Thanks.

Run 'em off separate 12V supplies if you can, at least from the main breaker panel (which should have a good heavy feed direct from the battery). If that doesn't clear it, then I would start to think about ferrite rings on the supply leads as a next step.
