Currently my TR186 has a Lowrance X135 mounted in the dash. It has a read through the hull Transducer and also a connection in the Ethernet port I assume is for water temp. Problem is the X135 has a burn out spot in the middle of the screen and needs to be replaced. I am fine with another 5” as I only really need this to read depth at higher speeds. I am hoping to be able to use the same transducer and other connections if possible to make the trade out simple as possible. I will probably buy another unit for GPS and better sonar unless I can a decent dash unit that would fit and work. Any help and advice from others who have been through this with the same type a Boat would be greatly appreciated. Thanks for all the help with this and my other questions on previous threads.
