BMW and M Power Owners

I used a UMIK-1 microphone to calibrate the time alignment, that made a huge difference. I tried using it to calibrate the EQ too, but it seemed to drop the 200Hz frequency right down (guess there was resonance or something?) so I tuned it manually, then my local sound guy tweaked it a bit more to finalise it all.

Can't change anything with an app on my version of the amp, had it for about 3 years now though.
good sign that it has proven reliable.

yes I had subsequently scanned the audison Ap4.9 manual (and tuning guide ) and concluded they only have a wired remote control that could be used to swap between
two eq/time alignment profiles, but I guess, could equally/cheaper whip out the laptop and load another profile.
.... £100 microphone on top of the £600 ap seems steep, so maybe, first, I'd try downloading some of the de-eq/eq profiles folks already created.

funding their usb/dac input module, to enable a direct digital input from a phone to avoid all the de-eq of sounds from the oem amp, sounds more interesting than the remote too.

these AP's are sexy pieces of kit though.

with a base audio system upgrade I'm wondering if the AP would need to go somewhere in the dash or glove compartment, I need to transplant the hertz speakers I have in my old car, too.

[ Does seem to be consensus that the centre speaker is trying to address absense of a idrive control for time alignment and provide a good compromise with multiple passengers.

Finally got my letter about the airbag recall to replace the fragmentation grenade currently fitted to the car, looking to forward to try to get that booked in any time soon :p
 
I've only just bought my car. 2017 4 series. Which years/cars are affected?

Hard to find much concrete information but anecdotally from what I'm seeing on owners groups, looks like it could well be pretty much any/all F30 based cars. It's been ongoing for a while now, hence my saying 'finally got my letter'.
 
Hi All

Took my car to get an oil change the other day at a BMW specialist garage local to me and they noted on the paperwork that "Boost pipe seal leaking (Turbo>intercooler) on the intercooler side"

I called the BMW dealership Vines in Guilford and they stated it would need to be inspected as it was a UAC but then also sent me a link below
https://www.bmw.co.uk/en/topics/owners/service-workshop/warranties/bmw-auc-warranty-guidelines.html?_ga=2.245664129.44653186.1646823252-1986158225.1610446463

I'm going to call my local dealer and ask if they can inspect and confirm if it falls under warranty? I'd say as I got the car back in January and don't drive it with a heavy foot at all it would be covered?

Its a 2019 530D - Anyone had this before where they try and wriggle out of a claim?

Thanks in advance!
 
BMW USB drive audio formats - idrive 5/6/7
seems I will need to re-encode my cd's ripped in AAC/256K to OGG/MP3/FLAC because bmw didn't pay for whatever license AAC had required -
OGG seems like that should be most efficient codec, although if I get at 256/512K usb drive I probably won't be too pushed for space.
I then need to compare quality between using a USB drive and having media local on a usb wired iphone(VLC player) and carplay,

Any opinions on which was best for you ?
1. USB drive
2. Wired usb audio from iphone
3. Iphone with carplay
