I have Pro HU, not CIC, but still have the PDC reduced sound issue..

If any of you has access to a voltmeter and a sine wave test track, you could test the output voltage. Any takers?

I'm unable due to travel.

Looking at http://www.e90post.com/forums/showthread.php?t=649952 this post, a guy with the same problem, It almost sounds like the outputs are low level which is why very faint sound from the rear. You guys 100% sure that you have a high-level signal from your rears? They are just as loud or almost as loud as the front???

I have no front to rear balance issues. It sounds 100% correct. With the Alpine Kit (PN ending in 268), there's no real way to install it 'wrong', unlike the old (pre 3/09) kit.

Well naturally you want a stronger front soundstage which is why the alpine kit isdesigned as is.

The stock stereo config maxes at 9v

Hifi @ 5v

So the difference is 4v.

Which translates to 43dB (9v) vs 38dB (5v)

So the rears will be quieter (than before) but not terribly so if they are running on the HiFi low level output.

However the relative volume as compared to the fronts will be quieter as you will have the HU at a lower setting for a given frontstage volume given the new amp

How much power does the alpine amp put out?

Thus with the alpine kit, even with the outputs being low level (if they are) the fronts would only be about twice as loud.

I'm not an expert at this, just used some online calculators, so I could be way off.

Has anyone successfully recoded a CIC nav from Base stereo to balanced line outputs?

I only ask again because I did see something about it in the coding spreadsheet.

Where is the coding spreadsheet?

taibanl · 11-27-2012, 03:54 AM

Coding subforum has links. Im not a frequent poster there so i dont know exactly

djbordie · 11-27-2012, 06:18 AM

anyone have success in coding a late model 2010 HU?

to hifi ($676)

mine is november 2010, (2011 e90) pro HU

im going to try it this week, fingers massively crossed

here is your sheet
https://docs.google.com/spreadsheet/...CPqY7sEC#gid=0

According to post #1 (by me), yes

Edit: this was done by BMW (ISTA/P) as opposed to NC-SEXPERT

djbordie · 11-27-2012, 03:43 PM

yes, but you went to a dealer...

do you have any details on the ISTA/P process they used?

im not paying a dealer 300$ to code to hifi...not an option

woodpecka · 11-27-2012, 10:37 PM

Yes I did it by using the last version of nc-expert and a cheap usb d-kcan cable from ebay. You must have the daten files v47.

I have been able to reset the radio and activating the usb by the VO. For BT, I had to modify the MAN file manualy.

ctuna · 11-28-2012, 12:48 AM

Can you list the VO and file changes
I assume you might have had to change the rad2 parameters.
Can anybody list the changes for going from L7 to Hi FI then back again
and does is it the same change for 09's and above.
Also what is the last version of nc-expert.
which man file?
What year car and what hardware were you working with?
mulf2 or something else.

There are two options (i am confident both have same net result)

Conversions: HiFi Amplifier
Retrofit: Alpine Hifi

djbordie · 11-28-2012, 08:04 AM

alot of guides and such say you can simply:

change VO $676 (or whatever you want, check the spread sheet)
write to cas

and then turn off car, wait 10 mins, turn on and it should make the necessary changes.

however different years and such have had different results.

there are a few nice pdf's floating around showing how to exactly do this process. Step by step.

If i have any luck on coding the easy way this week, i will make a video step by step to help out the community

there arent many youtube videos of ncsexpert, but certainly none showing the HU coding

ctuna · 11-28-2012, 12:54 PM

When you change the VO its CAS and FRM I think I know its been stated two modules have to be updated.

There seems to be a point where the radio changed around 09 and the actual VO codes may have changed and the related hard ware for phone , usb changed a few times between 09 and the current years hence the need to change the build date of the car to get it to accept the new programming for the newer hardware.

It would be nice to get this info stickied.

djbordie · 11-28-2012, 12:59 PM

interesting, ive never heard of this.

man its like voodoo magic trying to get hifi...but you want to close all your doors and sunroof with the fob?? easy...LOL
