No, we changed out everything except for re-using the 4 foot "antenna" instead of the 6 foot antenna the Max Marine unit came with.
The 6 foot antenna is hanging in my garage new in the box.
We were getting a "no spoke" error. Repair guy thought there was a bad part in the array which he changed out. Still didn't work which is why we got a different unit. Could have been the processor box, which wasn't available, but I had had enough at that point.
Feel like the 6kw units are problematic.
Newer electronics just aren't like the old Furuno stuff that would last and last, thinking 5 years is about the life today.
