Thanks Meindert,

My friends boat is being delivery from Rio Grande do Sul to Bahia next
month, and we definitively will try this, making a interface cable
based on your instructions.

BTW, the Raymarine site has the folowing information about the C80
Interface using a new free utility program to do this, using the Cf
card and Excel:

=== Transfer waypoint data between a Microsoft Excel file and
Raymarine C-Series displays.

Requirements:

Raymarine C70, C80 or C120 display

A Windows PC with a Compact Flash reader/writer

A Compact Flash Card. To ensure the integrity of your map data,
Raymarine does not recommend using the Navionics Gold map card for this
procedure.

Microsoft Excel



====To upload the wpts and routes from the CF card, the procedure
would be as folow:

Restoring Waypoints, Routes, and Tracks
If you had backed up data before the upgrade, you can now restore it
using this procedu

Insert a card into the card slot.
Press the DATA button.
Press the ARCHIVE & TRANSFER.
Press the RETRIEVE FROM CARD.
From SELECT LIST, choose WPT (Waypoint), RTE (Route), or TRK (Track).
The card contents for your selection appear on the screen.
Use the track pad (up/down) to select what you want to retrieve.
Press RETRIEVE ALL or RETRIEVE GROUP/ROUTE/TRACK as appropriate. A
message box appears to show that the information is being written to
the display.
When the transfer is complete a message will appear on the screen.
Note: Pressing the RETRIEVE ALL soft key, will retrieve all of a
Database list to the display.
