Sorry I put this on the end of an old post which now seess wrong.
I have the code, just didn't remember it at the right timebut it has locked out and does not want to unlock.
I drove to Preston and back from Boston. Waiting for "Code in" to re-appear but it didnt. If after waiting several hours I press the Band button, a second line of dashes appears at the very bottom of the display.
I have had the radio on the bench hooked up to both constant and acc supply for over a day now @ 13.8 Volts so the suspect low voltage on my car batt is not an issue, but it has made no difference so far.
Any ideas please? Is there anyone there who knows how to force the "Code in" sequence. I am happy to go inside the radio. I have tried shorting across the ISO connector pins but to no effect (I expect there are diodes in series)
Any one have a cct diag for this unit? Or know which is the memory capacitor (I thought it was non volatile earom not just a cap). I have now also tries shorting all over the pcb without the power on.

If only it was, but as I said in my original post, all that happens is that another line of dashes appears accross the bottom of the screen.
I am now wondering if the back emf from the starter motor stalling shot the radio up the backside.
The condition started when the battery was low and I attempted to start the engine. The starter motor stalled and the rev counter flicks round to full revs and the needle sticks against the glass. Also because the voltage drops to vitrually zero on the memory supply line the radio thinks it's been disconnected and goes into "Code In" mode. Had I remembered the code at that time all would have been well. But instead of leaving it until i could look it up i was convinced i did know it (which i do now) and didn't.
Anyone got a service manual for this Clarion radio please? my internet search has been unfruitful.
