I was happy with my system in terms of quality and sound but I think their claims are to be taken with a pinch of salt. I think, for just a system, you will do as well going to a power flow type place as they aren't cheap! My biggest gripe was the back box was an oval cylinder, the OE box is rounded at the rear and as such I grounded mine quite a few times!

On the 3/523i the perceived wisdom was an M50 325i TB, inlet manifold & a remap if I remember rightly the 23i is actually a 2.5 and strangled so as not to compete with the 28i. The rest I'd leave alone

The only option as far as I am aware will be the e34i 525ix with M50 which AIUI is a similar block architecturally to the M51. Though you say M57 earlier? 525tds suggests the M51 I'm still not clear what you are trying to do - fit and to an e39?!

If its any consolation my business PI went up 4 fold, nothing has changed "that's just the market" apparently.

Not dab but nearly every USB cigarette charger thing i have causes interference to the extent i've bought a noise suppressor to fit in my e39. Annoying i can't charge phone and listen to radio!

I had the full system including manifold on my m535i. I liked the sound but I don’t believe it did anything for power and the rear box used to catch on my drive (deep gutter on cross over) because of its shape where oe didn’t. If if I was doing it again I would consider having one made as its not the cheapest!

There maybe one for a nav unit though.

I have a diagram somewhere but after fitting a jack and getting fed up with interference noise i fitted one of these: https://www.ebay.co.uk/itm/Bluetooth-Handsfree-Music-Adapter-AUX-In-Cable-Fit-For-BMW-E46-E39-X5-E53-X3-E83/133414421623?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 select aux and find on bluetooth, job done. Only down side is that it doesn't auto connect but don;t suppose that's any harder than plugging in each time.

Yeh mat would be foolish after the effort!

Old post resurrection but i changed the hub carrier and bearings at the weekend when swapping out the dampers and touch wood clonk has gone! Can't say i saw a split - i've binned them - but i was getting movement of the top hat bush ie the splitter was pushing them if not very careful and the rim of the top hats were rusting away. Hard to say but its nice to drive on our shite roads clonk free!

Have you tried Tims on here for an original system? He will courier and a local garage should easily fit it perhaps with some new rubbers? As it goes i think i've only changed one BMW exhaust and that was on my e28 that had failed only replaced two blocked cats.

I'm also curious about the asymmetric roof of your house in a professional capacity as its quite unusual!

Whats the premise/ intention for the layout? big roundy roundy or something prototypical?

Thanks Dennis, I have the MID and CD - High OBC i think it is. Baris does the basic or BM54 nave set up as far as i can tell. I did ask when he did the pixels. I don't really want to spend any money if can be avoided so will fit the speakers and mounts i have and go from there.
