I've recently upgraded my entire sound system in my D40, and everything is working great, except for the steering wheel controls. I'm assuming all I need to do is locate the Bluetooth module and plug in the loop back plug.
Only issue is, finding the damn thing! I've looked behing the glove box...
Did you ever manage to find the module? I've been looking for two days and spoken to Nissan and a few audio installers and they have no idea where the module is in the car. I have a 2013 D40 ST.
