I would imagine your car is not wired for the logic 7, which I think would involve removing some carpet, seats, and some panels to wire up the logic 7. would your friend part out his car?

I would think one of the tougher things is that Logic7 has speakers in the rear doors - right? I think, just in general,
that retrofitting Logic7 isn't the easiest thing to do.
that retrofitting Logic7 isn't the easiest thing to do.
The only thing in my mind is: How much speakers has a standard sound system, and where are the extra speakers located??
Is there someone who knows the answer

Got, ACS Roof Spoiler, but not installed..
you will need the new logic 7 amp, located in the trunk,,,
you will need two rear door panels (so they have slots for new speakers)
you will need the 13 speakers from the logic 7 system..
(normal US/europe HIFI has 10 Speakers) (Standard in europe 6 Speakers i think)
you will also need some coding done by the dealer....
Logic 7 speakers are different than standard ones

The Logic 7 system has the 2 subs. Each sub is under each front seat. Not sure if the regular sound system has this, but if it doesn't, I don't see this being a very easy job. I think it would be smarter to just go with a new aftermarket system.

If it's a really hard job and i have to deassamble the whole car, i just swap the amplifier.

In order to retrofit L7, here are what you need to do, according to my understanding (I might be wrong):
1. Update your Vehicle Order (only BMW regional headquarter can give your dealer this) to have L7
2. Replace all speakers with L7 speakers
3. Add mid-range speaker to the center dash
4. Replace two rear door panel to accomodate 2 mid-range speaker
5. Add two mid-range speaker to rear door panel
6. Rerun wire for L7 all over again. Current standard system mid-range and tweeters are driven by head unit. Subs are driven by small amp in the left side of the trunk. All L7 speakers are driven by L7 amp in the trunk. Therefore, you need to change the whole wiring scheme. Seems like a tough job.
Does this sound complicated? Yes. Has someone done it? Yes. Please search the forum. I'm too lazy unless Rudy can help
Good luck.

In US, both L7 and standard systems have 2 subs under seat. L7 sub each rated 75W and standard each rated 45W (could be 40W, I don't remember well).
