Had the battery go dead recently. When we jumped started the car we noticed the radio would not power up so we could re-enter the code…checked all the fuse boxes to no avail…any thoughts? ---

I don’t know - but my thought is to ask whether or not the owner’s manual has anything to say about it. Lots of people don’t have their manuals in which case I’d say its worth your while to get one. ---

have you checked to see if you have power in the radio plug??? have you checked the fuse for the radio??? i have worked with systems and have seen when someone jump starts the car it sends a spike and will fry the radio
