I'm about to embark in installing the Pioneer Avic-Z2 into my 04 X5. It's the non DSP business head unit.

Big question is, can connect the head unit straight into the stock amp via a harness? Is there anything that I should be aware of? Like how to trigger the stock amp to turn on or needing a high/low converter? I know that the Ibus might play into effect.

I'm sure I'll be asking many questions along the way if I can't find it via "Search".

I'll try to post pictures along the way as well.

Thanks in advance!
