If you are trying to fit this radio to a different vehicle, then you may find yourself with the Error message of "CANCHECK". As well as having a conventional Radio Security Code number, this stereo is also electronically paired, or "Married" to the engine management system of the vehicle it came out of using very sophisticated CAN-BUS system technology.
When it is first powered up, it will communicate with the vehicle, and a message of "WAIT" may appear on the display whilst this process is in operation. If communication has been successfull, it will prompt for the Code number to be entered in the normal way.
However, if removed and refitted into a different vehicle other than the original one, it will not recognise the encrypted CANBUS identification of the new car, and will instead display an error message of "CANCHECK".
This Radio cannot therefore be transferred from one car to another, unless it has first been reset back into its original "Delivery Mode" with the CAN-BUS data memory reprogrammed for use with the new vehicle.
