Logic 7 retrofit coding

golden11lead · 04-06-2021, 10:13 AM

Hey guys,

Ive looked extensively online and everyone says something different.
I retrofit the logic 7 system in my car, and I dont get any sound.

The MOST loop is working as I can see the other modules on ista, i know its getting power and ground etc.

I changed thr VO, removed 676 and added 677.

When I try to code anything on the MOST loop I get errors.

2009 e92 335i non i drive(yes its possible without idrive)

Any suggestions?

Thanks!

Not having an ICOM cable for cars made after 3/07
K/D Can cable is only good for most modules up to that date according
to a lot of the coders.
Be sure Inpa is working before going on to coding.
See coding sub forum.

module's are different for the cic vs ccc

It turned out to be a dead amp- I got anew one and it works great! Thanks.

I have a 2006 325i e90 without idrive. I have the hi-fi amp with the BMW professional CD head unit.
I ungraded all of my speakers the logic 7 speakers. I finally got a logic 7 amplifier from a 750i model as I wanted to put more wattage to the subs and the rear dash.
Plugged in amp amd spliced in connector amd no sound.
I have a foxwell scanner programmer and I tried to activate the most rings new settings and the top hi-fi amp. Still no sound.
Frustrated, I removed the logic 7 amp and reconnected the original hi-fi amp.
My audio returned but now I have a high pitched wine when I listen to the radio stations but not when I listen to the aux input from my phone.
It almost sounds like a ground loop but I'm not so sure because its not present when using the auxiliary input.

In pretty good with audio systems but this most network thing is new.

In wondering if I messed up the coding somehow.

Any ideas or tips or new ideas are welcome. Thanks.
