Wondering if anyone has had this problem. My 1022 is intermittently stuttering for lack of a better word. The image is not smooth like it normally is and this problem comes and goes. First two days on the lake I had no problem. Then out of the blue this begins. I cleaned the contacts and I'm getting 12.5 to 13 volts. The black box and 1022 are both powered by a separate lithium ion battery. The screen will run fine and then start the stutter, then will clear up, then start back again. I can find no rhyme or reason. Any thoughts or better yet solutions? I did update it a few weeks ago no problems. Thanks ahead for any info.
