I'm getting the USA-Spec PA11-NIS and installation next week. I will need the bluetooth voice system and steering wheel buttons to still work. Also not to have any interference noise from the engine. Is there anything I need to tell the shop, or all theses features are already there?

 

it doesn't interfere with the bluetooth and the steering buttons will work for both the HU and the ipod.

 

How about engine noises coming out from speaker, especially when accelerate? I've had that problem when I've added AUX port on my Accord.

 

I get no noise.

 

You shouldnt have any of those problems mentioned above.
I did it myself and none of that comes to interfere with the connection and all.
