I'm not sure this is correct but as far as I know you have to keep the car running for 1hr or more in order to try the code again.Hi Dear azb786,
Thank you for quick reply,
I hope you could help me bit more,
radio continuously shows "Wait 1HR". Its was appeared yesterday when i was opened whole radio kit for serial number.
And still shows on display even i didnt try code yet. I have disconnected battery again might it helpful but didnt find any change.
Try 3997 or if that doesn't work 1997Hello
I have a 2008 micra and had to change the battery recently - and now the radio/cd player is asking for a code. I wasnt given a handbook when I bought the car and dont have a code. It is a factory fitted radio/cd player
Can you provide the radio code ?
As long as the radio is turned OFF when the battery is swapped over Mika, there is at least a minute (probably more) when the battery is disconnected that the radio retains the code, so if the battery clamp down bracket is taken off and both battery terminals loosened, BEFORE the old battery is disconnected and the replacement battery is next to the car a battery change should not require the radio to be recoded anyway........ (charged capacitors in the radio are sufficient to retain the coding)My battery died winter 2016 in eastern Finland at -26C, tow truck gave me jump start. At garage in beginning of battery change, mechanic hooked small 12V battery to cables of Micra. This way all electronics had power when vehicle battery was changed.
Mechanic said even small 9V battery gives enough juice to keep all settings stored during battery change
