You can dl a lot of upgrades does not change the unit out,I dont know the unit, I do know support.Often what one reads is conflicting on their web site,one does however have to read more info on page 2 frequently.
What I tried to do was buy a combo unit what i got was a chart plotter lacking the sonar as depicted.Ended up getting it working on my own,but rc small screen popup.My 80 dollar used wide vision gives a lot better pic and i got to use all those transducers I purchased that said they worked on both units that did not now removed from their website any reference to.So wasnt as much about the model as support.
I do know how to update my own units and do not follow their directions as older units ,on current ones would pay to follow the video.
Be glad to sell you two units still listed as supported 1/3 original price 755c and a 785c2i (combo)they are indeed good chart plotters to which that is now their listing.Say 200 for 755c 250 for the 785c2i to your door ea.
For what its worth they will continue servicing all units for 7 years after they go out of production,last made in 2010
260 bucks would fix it plus postage if it needed it( they may ask for a store recpt dunno),nor did he like paypal while many do not it is a guarantee to both parties since unknown party not unreasonable.
