Since my previous post about my problems with the LCX25c there have been some changes. Friday I tried the new 25c that Lowrance had sent overnight. Within 10 minutes the same problem appeared that was on my first unit. On Saturday the Lowrance rep drove to where I keep the boat in the water and spent over 3 hours trying different combinations of power leads, transducers and checking voltages, connections and everything else in between. The second unit had the same problem as the first. He then drove an hour round trip and got his own 332 and hooked it to all my cables and it worked fine. Apparently I had got two bad units. He is going to send all units back so I wont have to mess with them and is working with customer service to come up with a different solution. While I am disappointed this has been going on since at least June 27 (almost a month now) someone is doing something to help. I will let you know how this plays out. Anyone else having problems with the 25c?
