Have you visually inspected the Amplifier area(for water) and checked the
battery and alternator voltage.

Maybe your new Head unit is bad.
Also there is a idrive forum here.

I think also to the CIC,other it’s perfect

The thing that happens when you hit the gas is the voltage out of the alternator
may increase. Also loose connections could be moved enough to make contact.
What's your alternator output voltage look like.

Acceleration joggling or causing a marginal connection to go open.
If you are just setting in one place does this happen at all with the
Engine off and ON?
Try giggling wires to see if you can reproduce the problem without
the car moving.

[Mc 007]

With engine on or off if car is parked no problems,liw or high rpm is the same audio is perfect
Have try also to take outside the CIC and drive,same problem
Temp outside in the night is here 5 C’,maybe was 0 in the winter period
Maybe with warm weather will be better
I suspect the CIC,other components on the most have test
Have you see the video?

[ctuna]

yeah I looked at your video . It was playing then the sound just stopped and
I guess you where checking out the other Sources for Sound and found none
worked. I had a New Pioneer Head unit in another car and it wouldn't play on
a Cold Day and not all that cold like 40 degrees F . Exchanged it and problem solved.
I would think if you had a problem with to cold once it warmed up it should go away
though.

In summer time problem vanish,only in acceleration the audio vanish
Now temp is lower and the problem come again
Have take the CIC to a an electronic repair shop and they haven’t find nothing…
Thx if someone will help
