One of the girls in my office bought this for her husband 2 years ago fo his boat. Well, he came down with cancer and sold the boat. She found it in her closet, they had forgotten all about it. Anyway, she paid over $300.00 for it and I explained that she won't get that much out of it now. She would like to get at least $200.00 for it/ It is BRAND NEW never been out of the box (heck, the box was still sealed until my daughter opened it up when I wasn't looking ! )anyway, everything is in the box. I don't know anything about this unit other than what is on the box. It would make a nice addition on YOUR boat. PS. This is not mine, helping out a friend.
