Good morning . I just updated the software to 3.110 on my Onix! Lo and behold mine has problems supposedly fixed by 3.110. Problems I have not seen before. Problems with 2d and showing the chart. I have defaulted to factory setting numerous times. The power cable is an 8 gauge with all Burndy copper crimps. Voltage drop on the power cable is negligible. It was back in to Humminbird for screen replacement and the various Onix issues in May. It went out of warranty on Jan 16, 2018. Just waiting to see what how well they take care of me. Like many Onix units it was never trouble free. I understand that all brands have issues at times but this is three years they have had to fix them! Sorry for the rant!
Happy Fishin'
