Not to my knowledge, but should be able to get one designed for a Gen 4 to fit with enough modification of the mounting points. They were never a very good seller, which led to Whiteline discontinuing it.
If they both have central locking, it should be the same. If not, then you might get lucky and the wiring will be there. I have found that Toyota weren't overly consistant with wiring between different trim levels.
Have you tried unpairing it on your devices? Depending on the headunit model, it should be under the Setup menu as Bluetooth. From that you may have an option that says List Phone. You should be able to delete it from there.
