I have the elite 4 on my dash, which is what I use to find schools then I pinpoint them with the bow unit. Set it to sonar only page (not dsi split), advanced mode, manual mode. Black/white/blue FISH REVEAL color palette. Set your depth to auto, amplitude scope on, colorline 52%, and sensitivity to around 60% and adjust from there. If the signals are weak, go up, if you get a screen full of red/orange then go down in sensitivity until it clears up and you can see the individual fish. Now drive around and get the sensitivity dialed in and look for fish! They will not be perfect arches like you see on the box, most likely dots or small lines depending on how fast you are moving and what your scroll speed is set to.

Good luck, it takes time on the water to dial it in but you will get it. After a couple weeks of marking fish and catching them you will learn to ID what kind of fish they are just by the way they look on the screen.
