navionics chip

Trying to muck with the chip OUTSIDE of their system can render the chip useless, and they WILL NOT honor any warranties.

They have some pretty specific rules with regards to that and perceived threats against attempting to "copy" the chip.

I called their tech support and asked about making a backup and they told me they don't allow it.

They're encrypted & if trying to copy them they can become corrupted & useless.
