Ipod integration E70 2007

[dogfooddave]

I have a 2007 E70 with an aux in for ipod. I find the sound not good. Far better sound from cd player. Is there a kit available for the E70. I notice kits available for previous models but alas none for the E70. I have searched the threads here and not found satisfactory answers. I notice a Dice Silverline introduced for E70 but it doesnt seem to be on the market yet, testing for bugs I believe. Can anyone tell me the progress on this kit. Is it on the shelf or has it been shelved!
I just want my ipod to play on the X5 with the same quality sound that I get from the cd player. This quality is not there using the aux in.
Appreciate any help.
Thanks
