[2008 323i]

I was wondering I have a 2007 328i with logic 7. I don't have idrive.
I was wondering since the deck uses fiber optics can I buy a aftermarket deck with fiber optics and just plug it in?
I have the wheel controls also is there a deck out there that can use the pac controls so I can use the steering wheel and the factory amp????
clarion has drx9255 fiber optics but no pac controls
anyone know of a differnt company that makes both

pac/fiber optic
please pm let me know what you have used

The OEM HU fiber optic transmissions are BMW proprietary (MOST) and the digital in/out of that classic drx9255 is only for Clarion peripherals, also proprietary...

I know it's pedantic, but MOST isn't BMW proprietary... it's just a rather uncommon standard

Porsche, Audi, and Mercedes also use it, and there are a few third-party accessories appearing that support MOST interfacing (notably the Denison Gateway 500).

I doubt you'll ever see it in an aftermarket HU, though, because it would vastly limit the number of accessories you could use with it.

Stand corrected... I was not clear in implying that, although the network is MOST, the data transmitted itself is BMW proprietary.

that is true, just channel allocating within MOST is individual, that means how to use MOST is dependent on user, therefore, BMW, MB, VW usw. are different all but the name MOST.

ok looks like I will need a new amp has anyone used the pac setup??? does all the buttoms still work on the wheel : track and volume?

[wheelman2925]

I've never seen anyone w/ a working PAC setup in an e90 w/ logic7. I've decided that headunit replacement is not worth losing steering wheel controls, esp the phone. The OE headunit is far too integral to certain functions to make removal worth while. I'd really like to have a full featured head unit w/ dvd, dvd-audio playback but 99% i listen to CD's or a HD music player. I decided to add my own amps and speakers and wait for a real working solution to emerge for retention of steering wheel controls etc.

If you are planning to add an amp to your Logic7 then it will need to be added after the OEM amp, as you cannot remove it. And to do that you will need something more than a plain line level converter, you will need a summing and normalization device.

I plan on keep the stock amp to power the speaker and the other 2 amps to run the seat subs and the 12" sub in the rear.
I have not replaced the stock speakers
just have to save for a couple of sets of focals
what line level adapter are people using???

[VP Electricity]

The Zapco BTL feeding a DC series amp.

BTW, cheap transformer-based LOCs are high-pass filters... bad for bass.

I aready have about 5 amps at home all older phoenix gold
Frank amp n stein, Route 66, Msp2500, ms 275,M25 all of these don't have line level so I need to add one
I just don't want a $10 one and make the bass sound like crap!
