guys i'm about to do the following to my 2003 2.5i z4 with hifi system (10 speakers, amp at the trunk, without dsp):
1. change my hu to pioneer p99
2. keep using the stock amp and speakers (hifi system, no dsp)
i've been back reading and some posts says i cannot use an aftermarket hu (gvbelgium, reach) while others have posted it worked for them (blacksapphirez4 and strokez)
if i understand correctly, all i need are the following parts:
1. scosche z4 radio bezel kit link:

2. scosche bmw link:
http://www.scosche.com/car-audio/product/691
3. antenna adapter link:

to intall, i just have to plug the antenna power to pin 13 to power on the stock amp correct?
