I previously had an AVIC-Z130BT. I still have the CDP1425 cable that came with it. This cable is the one that has a USB and 3.5mm connection on one end while the other end connected to the Z130BT's IP-BUS input.

I mounted the CDP1425 cable (the USB and 3.5mm end) in the dash of my car.

Can I use this cable (CDP1425) with my new AVH-P8400BH? The AVH-P8400BH also has an IP-BUS input that the CDP1425 could connect to.

Anyone?

According to Pioneer's parts web-site, CDP1425 is only used on the AVIC Z1x0 and X9x0 models.

The AVH-P8400BH uses CDP1435.

Might just be a minor change. You're not likely to find someone who's tried using the AVIC cable with the AVH, so I guess you'll be the guinea pig.
