Just purchased and installed a Lowrance Hook2 7x GPS Splitshot HDI.(no charts) Followed the set up instructions on line, easy and straight forward ( the book that came with it has 9 different languages but no English! Go figure!) but nothing is working properly on any screen. Sonar is all vertical lines and depth display in jumping back and forth with ridiculous numbers, GPS doesn't track any movement and down scan imaging screen is solid blue. Transducer is installed with military precision! I have installed and set up so many through out the years through the business without any issues ever though I am at a loss here. Even tried operation with engine off to eliminate electrical interference. Any suggestions folks?
Thanks in advance,
Mike
