Has your battery been disconnected for a while? As far as the radio and clock, often when they don’t get any electricity they stop working. Its a security feature meant to dissuade car radio thieves. You have to enter a 5-digit code that hopefully is written in the manual , or you can get from any Acura dealership. The radio display would read CODE . the code is entered with one of the knobs. It is entirely numerical so turning the knob will get you digits 0-9. Its a frustrating problem that many people, especially those who bought a used Acura in a private sale have, so even if it doesn’t apply to Terry’s issue, I thought I’d mention it here.
