This might help

But I take no responsability. Might be the same issue in your car.

i dont recommend doing it yourself but the wire needs to go to a live fuse that works even when the ignition is off, ie, hazard lights, main lights, horn, etc

Is this the first time a radio has ever been fitted in it? Is there a radio loom for the radio being replaced?
#6
nope they tried swapping the wires red to yellow and yellow to red and its still the same ?
anyone else got ideas??

no its a second hand stereo my dad bought for his brava so its not the first install, and yes i think its best to take it to a garage

Is there a loom with a plug fitted in the car where the stereo should fit? If this is a standard loom plug then the wires will be easy to ID - power igntion, power, antenna, speaker L and R etc. Make and model of stereo?

You usually have a permanent live that keeps the stereo memory (clock, settings etc), then the ignition live that powers it up/down with ignition.

All cars should have this. If not, someone has tampered and possible used it for something else (mods?).

Get a multimeter.

Find constant 12 v power source, then cut wire from radio loom and attach it to that (i sometimes just strip wire, then tie it round and tape up using electrical tape)

Find the ignition wire by turnining on the ignition and finding a 12V power source. When you turn it off if there is no power you have your ignition wire. Attach the red cable from loom to that wire

So you tried to start the car, it wouldn't start and you thought, I know, I'll try pressing buttons 1 & 6 on the stereo oO

Have you just fitted the stereo and was it connected with a ford to iso cable?
