Just updated a gen 1 solix 12 and 10 to 3.9 update. Units were working great prior to update. Now my primary unit at console the 12 is not being recognized as the primary unit. Can’t make the 12 in source setting to be recognized. 2d and down imaging are using the 10 as the transducer setting. 2d and down imaging show no pinging. The on off slide won’t respond nor will it let me use the 12 as my source. Both units are wired direct to battery with a switch for each. When I cut power off to 10 the 12 is useless. Update was successful. 12 is also not showing same temp as 10. 50 degrees on 10. 18 degrees on 12
