I have the SRX system with the mute, on / off button and led lights mounted in the ashtray ... with a manual transmission, I am used to this sort of hand position while shifting, therefore the time needed to hit the mute button is not a factor.
The lighted unit is in the glove box where the CD holder used to be.
The audio warnings are more noticeable than the lights, therefore the green / red led status lights are not necessary to be in a highly visible location.
Being able to hide the whole system with the ashtray cover and glove box door leaves the integrity of the great looking carbon and leather options intact.
