Currently, I have a Kenwood deck that has RCA aux inputs. So I'm running a 3.5mm to dual RCA cable so I can listen to the tunes on my blackberry (16gb micro-sd card). But I also have to connect the blackberry's usb port to the cigarette lighter to get power.

Is there some type of device (i.e. Blitz) that can use just the blackberry's usb port to get sound and power?

I have an email into Blitz as well as Ice, but I was wondering if you guys have any knowledge about this.

thx!
