So you currently have the OEM Navigation unit installed on your car and you are looking to replace it with another factory OEM Navigation unit? I would say that you can replace it with the same model without issues. The model of the Navi unit is printed on the lower left corner of the screen bezel. If you are replacing your current navi unit with a different model, there could be a chance it does not fit. If you currently don't have the OEM navigation unit installed and are looking to install the OEM navigation unit, you are going to need a few more parts than just the navigation unit itself.
