Im pretty sure a business cd radio form an 03 is plug n play. I did my boss's car this way but it was an E39. He also wanted the aux in for his ipod and i did nothing but get a later version radio and hook up the kit from BMW.
Edit: the antenna hook up might be different,but there is a kit for that also. but anyway who da F listens to radio these days?
Not sure I agree there.. most of the time it still seems possible to find a tasteful aftermarket solution, at least for cars that aren't tooo new. It's like car companies realized people were replacing their headunits & specifically started designing dash's so nothing but factory could possibly fit/look nice, heh. That said, many newer systems have much better sound quality & features. Sadly, cars tend to be pretty crappy now otherwise, haha.
Wow, shelling out 10k for a stereo in a car, which probably is about the worst place in regard to interference, really isn't that smart... Now, that monstrosity just takes the cake... And you question his sanity... :doh:
Bare in mind, atleast 2-3K was used on Dynamat and different vibration absorbers.
As i said, this was an early build, very messy indeed, question my sanity then, sure.
But if you have to travel 6 hours every 2 weeks by car, you need something to keep you awake, it's also great for having tunnel parties and stuff..
But this was just to do a quick installation whilst the box was getting built.
The case, Before i removed it, was very very 'descrete' compared to this, amplifiers hidden behind the seats, aaaand just about 142db on Digital out, on 50Hz. AUX started messing about at 132db and wouldn't play without the stupid minor 'crakling' and static noises on lower volume.
It would obviously reach 144~db with Bass Race SPL CD's.
But my stereo is out now, and doing a turbo convertion, so pics to follow when done.
