Aye Joe camera was already fitted to my car when i bought it,garage that sold me car had no idea it was there and there was also a rear view morror monitor fitted over original mirror they hadnt noticed either,i think because it wasnt working is the reason they didnt see it,i first noticed the mirror when i adjusted the mirror and it came of in my hand but the wire held it in place(original mirror still in place) that got me thinking what this was and googled it turns out it was a rear view mirror with monitor so i looked at rear for a camera low and behold i found it disguised as a number plate light with light too,i then got to work on finding out why it wasnt working,turns out camers was already wired to reverse wires and had a transmitter attached,the monitor was hardwired to interior lights but had no reciever so i had a couple of video cables hanging around the house so joined them together via crimps and good old insulating tape to give me enough length to run it through boot along the car floor up into dash along windscreen and along the top where interior lights are plugged the other video end into monitor put ignition on car into reverse and up came the picture clear as day,a right result i think!
