If you are trying to fit this radio to a different vehicle, then you may find yourself with annoying BEEP
every few seconds. 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 VAN-BUS system technology
your can try but only if it was in the car from the begining
leave turned on untouched for as long as it takes to reset itself
