Some questions on replacing the stock head unit

Hello all,

I am planning to replace my head unit with an aftermarket pioneer one in my E89, but here I have several questions and would like to advise from some experts.

1. I tried to find out if my system has DSP or not, but still not 100% sure if it is. Then I tried to locate the amplifier to confirm it, but I searched google for a long time and still do not know where the amplifier is in the car, does anyone know?

2. I want to retain the parking sensor as well as steer wheel control, and plan to use Connects2 interface, anyone know if I have DSP system it will still work or not?

3. My local shop told me that changing the head unit will not retain the stock amplifier I would be using the amplifier built in in the new head unit, is that true?

Hopefully someone with similar situation as me could answer these questions, appreciated!

We have a similar problem on the E85/86, but solutions might differ.
