Alpine question
 

I was just wondering if the alpine DHA-S690 will be plug in play for my 2005 x5 with nav? my car didn't come with a cd changer... which one should I get?

There is no interface I know of for the DHA-S690, unless you fit a full vehicle hub system, however it does come with a remote control so you can use it without any integration. It uses AI-Net so it's possible that the Intravee may support it in the future but it does not right now.
