If your Dash looks like this one, this mount plate will fit.
Please Note : If you measure from the inside top edge of your steering wheel and the Dash Plate and
it measures 6 1/2" or more, then you do not need a steering spacer. If your measurement is under 6 1/2" then you will need a 1 1/2" Steering spacer. You can get it HERE.
If you have smaller units that are not listed in the drop down menu for GPS/Sonar, then go to the Z175/Z185 Single Dash Mount
Disclaimer: The Apex Factory Gimbal brackets have a Hole Pattern in them that "Does Not" match any previous hole pattern used by Humminbird in the past. We will send a Hole pattern with mounts that have a Apex model graph and you will need to mark your factory Apex gimbal Bracket and drill 9/32 holes them to match our pattern. Note: The BBT Cheyenne Series Apex Gimbal Brackets will have the same hole pattern in them as Helix and Solix Gimbal Brackets.
