Ok, Lowrance experts, need help. LCX25c on dash. 332c on Front. Networked with two temp sensors. Front unit picks up one sensor. Dash unit just blinks 32degrees constantly. Questions, assuming networked correctly.1) Should I be able to read BOTH temp sensors on both units?2) Can I name them….”surface” and “livewell” or something similar?3) Will the units automatically pick up sensors and display them, or do I need to establish contact in the Menu?
