remove battery

Hi guys,
I pretty new to the micra sceen but have some experience in audio. Just a quick Q. I have a K11 and some time ago my mechanic took the battery out of the car and replaced it with a new one. the only thing was that he had to re-enter a code into the engine to make it start up again correctly.

I want to add an amp to the car but am afraid of connecting the power cable whilst the battery is still 'Live'. Can I remove the negative post of the battery without any problems??

Cheers

Dan

What model do you have?

Normally with the stock radio in a k11 with nats the code is sent from the ECU to the radio to turn it on.

Perhaps k11 without nats would have a code for the radio.

With my k11 (with NATS) the battery can be disconnected and reconnected without entering any codes etc.

gotta go to nissan and get the code from the chassis number....

or get a new radio....

stupid me!! sorry we were asking something completely different...
I have wired amps and things without disconnecting the battery but it is not recommended.............

Hi cheers for the feedback. I have installed an aftermarket radio in the micra k11, the basic model from 98. I just don't want to have the hassle of bringin it to a mechanic. Would I need to get any codes? And if so where do you enter them?
