Hi
I am installing it in the cruiser at the moment.
It is in the car and working, still the camera wire to run to the rear, a couple of wire to connect and facia to refit etc., but have tested it all ok.
One of the wires on the loom out of the radio says "Brake Input", a blue wire, this has to be earthed, either to an earth on the radio / mouting brackets, or, if wiring correctly to the handbrake, giving an earth when the hand brake is on. If not you get the message you are getting.
I also had a Mini Digital TV Set Top Box from Dick Smith, (a little bit larger than a cig packet) laying around, so I have installed it via the AV Input RCA jacks at the rear. Works ok on the desk with the house antenna when tested, but the 3" magnetic antenna isn't much good out here in the country, but may work in area's with stronger tv signals, ........ just something to play around with !!!!!!!!!!!!
Cheers
Neil
