Ronny,
Rickie is spot on with waiting for the unit to finish booting before exiting the disclaimer screen.
For the darker left side Si sonar we need to see if there is anything to the left of your HDSi transducer that could be blocking some of the Si sonar. Many times it is the motor itself causing this, so the next time out you can try trimming up the motor to see if that helps. If not; post some pictures of the transom and transducer area of your boat. We need to see an overall picture of the transom and some from each side of the transom looking across from the left to right side and right to left sides. These all need to be taken at the same height as the transducer.
