How can i make my car radio come on when i start the car?
Answers:
The radio should have a 12 volt accessory and a 12 volt constant wire. Make certain both are connected properly. It sounds as though the 12 volt accessory wire is connected to a constant power source. Looks like they made a mistake when they put it in. Bring it back to the dealer and have them do it properly.
If u have it installed properly it should do it it self the power wire on the radio should be installed straight to the battery wire, and the acc wire on the radio should be wired to the ignition switch so when u switch it on it come on
Not 100% sure but my Vauxhall Astra did he same thing. Read the manual and fiddled with buttons andnow it works fine. Just read the audio manual
leave the radio on when u turn the car off
