Hi Flynn, We are sorry to hear that you are having troubles to connect and sorry to see that you did not reach out our support if you do have any situations trying to connect. To clarify here the unit is under the warranty so if not working as supposed we will replace the unit under the warranty. FYI the 2007 Camry and 2004 Land Cruiser are not OBD2 compatible so will not work. The pin in general is 0000 or 1234 however can be different (as per your device. Andoid settings). See the AX2 step by step video guide here If still no luck please contact our support.
