If your dash looks like this, then this mount will work.
This mount fits Nitro Z8 and Z9 models.
Please note: If you have a current sonar/gps unit mounted in the dash, please list in the box below. If there was no unit mounted in dash, please write "none".
If you have very large units and it is not listed in the drop down menu for GPS/Sonar, then go to the Nitro Z7/Z8/Z9 Single Mega Mount
