After jumping car my radio won't work. I'm
getting a code on my screen
anti theft , once radio circuit is disconnected it go's to a you need a code number to re activate , remove it and look for a serial number some Honda dealers have code books , hope some previous owner wrote it in the operators book if you have it. I doubt anyone ever stole a Honda radio anyway, a guy on just ask sold me a correct 5 digit code for five bucks years ago ,
Your lucky nothing else quit working, anything after 2005 is very power sensitive, if the main power drops completely out the BCM can loose its factory presets, and that makes you go to the dealer to have the system reflashed, so make sure that battery is at 100 percent, with hotter days approaching a weak battery will fail. If the battery fails the testing, make sure the place that is changing it out is using the right preset saver tool for your vehicle.
