navman 8120 card reader problems
Any electronics experts on here?
1. My navman 8120 uses cmap card but when I stick a card in the reader it just says no card present....my friend has taken it apart and changed the ribbon and cleaned off a bit of corrosion on the connectors but it still isn't registering...any ideas?
2. What's the best way to fit an in hull transducer...does the transducer have to actually be in contact with the hull? Presently the frame is glued to the hull and the actual transducer screws into that..I don't think that comes in contact with the hull though
Thanks for any help
