i installed the AVN726e too and i have the same background noise. Did you use the metra wiring harness with the RCA jacks?

I don't really care since i am installing an aftermarket amp in 1 week. I am pretty sure it has to do with double amping, using eclipse speaker outputs into the bose inputs. Adding more harmonic distortion.

 

i plan to make the upgrade to this head unit too. can you tell me if your G35 had the premium package or is it just standard? i ask because i have the standard 07 G35 so i do not have the bose speakers, instead i have the standard stock clarions. i wanted to know if you had to install an amplifier or does your AVN726E drive the speakers?

anything bad you can mention about this head unit? any interferance or unwanted noise from it? any info would be appreciated, thank you.

 

i have a auto as well how did you get the aftermarket **** on there? and do you have to press a button? and where can i get that ****?

 

Hi, I recently bought this same headunit and was wondering what steering wheel control harness did you buy and from where?
