Removed in full working order last year from a rib I refurbed.
Unfortunately I do not have the transducer or GPS aerial as they stayed on the rib with more modern units.
Not really sure what they are worth so open to reasonable offers
Not sure what the data cable is but I have the main wiring that goes onto the jack at the rear of the unit. Then there is the BNC jack at the rear of the unit for the antenna which I haven't got.
Thanks, although mine is also a 128 it looks different at the back! Does the main cable have about 7 tiny wires, blue, red, yellow, brown, white, black?
