Sounds like the unit was not wired into the car properly..the dealer needs to make sure that the switched lead that they connect the red wire from the radio to is hot when in both run and aux(accessory) positions on the ignition switch...it sounds like they may have wired the switched lead to the wrong accessory lead
your cd switch wire is not recieving any power. when you turn on your key it turns on the switch wire. the wire/contact on the ignition barrel may not have been connected properly. check the wiring and the barrel again
if this doesn't work connect the yellow and red wire at the back of the radio.it will work without the keys now
I had this problem for the last 2 weeks, didn't think much of it, but recently the car radio just turned on and off by itself, it decided to do so whilst the car was switched off and it drained my battery. After doing some tests with the Amp meter and removing the fuses for the radio and infotainment system the amps going through the batter went from about 0.7 to 0.001 (far more accpetable) - so the radio was draining the battery and randomly turning itself on/changing stations and the internal display system had stopped working.
after putting the fuses back in and re-testing the radio worked fine (almost like it had a full reset - no random turning on and off OR changing of radio stations)
the fuse box for my astra was next to the battery under the bonnet (see your car manual - I had lost mine so googled for it)
but it seems yanking the fuses for the radio (FUSE number 35 and 36) seemed to fix it (been a few days and no flat battery) -
It maybe an intermitent fault, in which case i'll have it looked into, but as garages charge an arm and a leg i'd give this solution a go and if your battery is good all you need to do is remove the fuses and put them back after say a minute or so)
you need to remove the radio and swap the red wire for the yellow wire and vice versa, they have bullet connectors to allow you to do this, basically the permanent live and the ignition live are the wrong way round.
