Hi all I've been advised this is the place to come for answers regarding Nissan cars so here goes. Can anyone answer this question please, I own an almera n16 sve 1.5 / 2005 model and the cd p[layer is not working { cd stuck and won't eject } so as a result I'm going to remove it for repair . Unfortunately I purchased the car off my father in law and he gave me three radio code cards { he has owned a few nissans } and he can't remember which one , if any is the correct one for my car.The car is fitted with sat nav and the clarion cy460 cd unit ,nissan part number 28185 bn810 /model number pn-2598m. So when I remove the cd player will I have to enter the radio code when I put it back into the car or will it be automatically picked up by the cars ecu as it's the original radio for the vehicle . I've read somewhere that the car will recognise the unit and no code will need to be entered. If the code does need to be entered how is this performed , reading the manual it states to use buttons 1 to 4 pressing each button the correct amount of times for individual numbers then to press the ^ button to load but my car doesn't seem to have this button so how do I enter the code . Do I use the sat nav/ radio knob with enter written on it the knob in between the map and info button . Many thanks in advance for any advice, it will be greatly received thankyou
