If you have no chart card for your local area, you definitely need one! As far as getting various data on the screen, as long as it is available on the system, you can display different kinds of data by pressing the "data" button and then following the steps to add data to your readout.

You haven't said if you have a DSM fitted ( sonar unit and tranducer) the C70 is only a multifunction display unit MFDU you then put a card in for navigation, a radar aerial/ scanner or a sonar unit for depth and fish finding .
if you have a sonar unit and it's working then
press Depth Digit and select on / off
press OK or cancel to return to the default display
hope this helps
It sounds like the fault is within the plotter itself. There should be any component, which shorts with main power supply, causes the blow of fuse to overload. I do advice you not to try to repair it by yourself, and contact the authorized service center. Gopakumar Gopalan Google
Sophistacated testing instruments are needed to repair this type of devices.
jmiller, Sound like your getting turbulence from the hull or your angle is allowing cavitation under the transducer. Look under the hull where the traducer is mounted and look for a part that has no obstruction including saltwater pickups, hull relieves, etc. The other thing to check is to take a strait edge on the bottom of the transducer to ensure the angle is slightly forward than the hull.

A test bucket wont work, A 200 khz transducer will generally not work in anything less than 2' of water, due to surface clutter. If the transducer is working, you should hear it make a ticking sound.
When you got the 17000 foot reading was your range set to auto?
How is the transducer situated on the boat? Sometimes turbulence and bubbles from the hull can cause erroneous readings, including unrealistic depths, or no depth at all. Stop the boat and turn off the engin e and anything electrical to see if problem repeats itself. If it only crops up when the boat is moving then it is most likely the transducer location.
Remove all wiring from 4000 head, hook up only 12V, if seatalk fail continues, it is the head. if seatalk fail goes away, hook in instruments one by one until the bad head is found. Seatalk is 12V red, Ground Screen(bare wire) and Data yellow (pulsing voltage).
Depending on your transducer type, you may have a liquid filled type that simply needs refilling. If this is the case check for leaks and get it redone. If not it could be transducer placement or cavitation under the hull.
