I have a GMR 21/41 that is not recognized by the 3206/3210

Customer Question

I have a GMR 21/41 that is not recognized by the 3206/3210 chartplotter on power up. I have gone through the screens but cannot find a setting to allow it to spin-up. I can see a radar line on the map but not a 360 sweep.

Hi there

Expert:  Pete replied 9 months ago.

Did it work ok previously, or are you setting it up for the first time?

Expert:  Pete replied 9 months ago.

Hi, I haven't heard back from you yet - please reply and let me know if you still need assistance with this.

It worked previously. It has not worked since relaunching the boat this year.
Customer: replied 9 months ago.
The drive belt is good. The single radar strip on the display moves in relation to the map as I maneuver the boat.
Expert:  Pete replied 9 months ago.

This problem is likely caused by a loose or broken cable.

I see that you have already disconnected/reconnected inputs - have you checked all cables and wiring for any sign of corrosion or damage?

Hi, just checking in on your question, do you need any further assistance?
