Thanks guys!
I watched for input and output when replacing the cables and I believe if you don't do it right the green light on s23 and s24 won't come ON.
The car call light will not stay on when I place calls through UIT.
As for LM24 board I searched for it and couldn't find it in COP,the only boards in cop are s24 s23 ,PI boardand CWIL boards and I already replaced the s boards and awaiting for CWIL board to arrive ,no other fuses found in CWIL board beside the pico fuses and they are fine
