I recently replace my HB385 with a Helix5 with GPS and 2D sonar. It is running off the I-Pilot universal transducer, The sonar image goes from sharp color contrast to a washed out brown/white image as I am running the TM. Don't think it is the transducer because the 385 worked fine with this setup. Only reason I replaced the 385 was to get a bigger screen. Here are a couple of screen shots.

This is the washed out display.

This is as it is changing from the washed out pattern to the full color contrast.
Have I got a bad unit or any suggestions as to cause? Only had it a couple of months.
