Oh, ok
But i have another question , I have bought the KDC-W7534UY with the phatnoise
but i dont have the DMS Should I Buy one or when i had bought the KDC - W7534UY the store should needed to give me the DMS
I think what you mean is that your Kenwood stereo came with Phatnoise
software. That is to be used for creating MP3 CDs or organizing MP3s on a USB drive, so they will function properly with the ACDrive feature of the Kenwood.
Is that what you mean? If so, you are not missing the DMS or any other part. If you mean something else, try to be exact.
