GD-1720C C Map - reprogram for Navionics?

GD-1720C C Map - reprogram for Navionics?

Postby paterbil » Thu Jun 29, 2017 9:07 pm

I am using a 1720c without radar, and have a fishfinder attached as well.

The plotter was set up for C Map, and I read here that there are plusses & minuses to reprograming for Navionics.

Is there a tutorial that outlines the steps to convert?

Also any opinion as to whether a 'converted' plotter does or does not handle the new card as well as a plotter that was 'native' Navionics (in this case).

This is not about C Map vs Navionics, rather about the conversion difficulty and any loss in the machine's functionality.

I will supply version # & serials if they are relevant.

Thanks

Navionics no longer supplies chart cards that will function in the Navnet system.

Thanks for the prompt reply, but it doesn't address the question of converting the plotter to accept Navionics.

The burden of the data is mine, can the hardware be adapted to accept something other than CMap?

Thank you again.

Yes it can, but it would have to be sent to our service facility in Camas, WA.
