Recently bought this beautiful used unit. Came with LCG-3000 gps antenna which was missing a resistor. I ordered two of the 120 ohm resistors and replaced both of them. Also came with a new 200khz transducer. I haven't installed it on the boat yet, just been playing with it in simulator mode to learn all about it. Didn't come with a manual so I'm doing what I can. My question is it states in the specs, etc that the unit is pre-loaded with MapCreate USA Topo and a couple of other digital maps....how do I access those maps? Also is Navionics the best way to go for digital mapping? I'm looking for a particular Lake in SC that they have. Wondering if it was worth paying the $ for.
