From what I see, to upgrade the stereo on the 5 series I a little bit of a challenge, especially if you have navigation too. The dash didn't have the cutout that is easily replaceable by any aftermarket single din headunits. You have to make a custom plate to accomodate your new headunit. And if you get the NAV, that's even worse I guess, there is no room to put aftermarket headunit, unless you cut the tape player, and install in there.
The system integration will be suffered too if you upgrade your stereo. Just my thought though.
So, if you don't think you want to spend like $5000 dollars for a really good aftermarket audio installation, I think you better of using the BMW DSP audio system for $1000, and saving you time, money and the hassle in case something is going wrong with the installation of the aftermarket unit.
I am a diehard audio freak also, and I planned to upgrade my audio system on my Acura Legend. The legend is very simple, and have the proper cutout to accomodate until double din headunits, and not too many integration like the BMW. That's why, I don't like the regular system on the 5-series that I had now, but I don't want to upgrade it, because of all the hassle, and sometimes custom works didn't turn out really good, and cost you a fortune.
