Largest Lowrance unit with out modifications

[jlittle1274]

I have a 2010 Z8 with a stock Lowrance x135 at the console. I also have a Humminbird 998 at the console with a Ram mount. I strickly use the Lowrance for 2D sonar and depth readings at high speed using the hull mount transducer that came with the boat. I have been having issues with the X135 lately and would like to replace it with something in color so it is a little easier to see. Again this one will be used for 2D sonar and depth readings at speed. What is the largest unit I can use without making modifications to the console and still use the current hull mounted transducer. I'm looking for something strictly plug and play. Thanks in advance for any recommendations and if you have some pictures that would be great too.

If I remember you could fit and HDS 10 on the 2010s. Get a precision sonar mount and do not worry about cutting.

I had an HDS12 in my dash at the console with no modifications on me 2013 Z8. Not sure if layout was different on a 2010.
