I already have XM & BT with the Stock system and my question is if i want to utilize the XM & BT with a new Z1 or D3 will i need to buy the XM & BT adapters or would i be able to hook my xm & bt to the new DD unit?

thanks!


Also if i can get the Z1 for $1200 and the D3 for $750 what would be the reasons to spend the extra $450 on the Z1 besides the 6 disc changer???


thanks again!!

 

a hard drive. you don't have to swap out the nav disk with a cd everytime you want to put in directions. and a little stuff here and there.
