How does the 396 interface with your headset for the XM radio?
The 296 allows you to order a "motorcycle" cable that will hardwire for both 12v (or 28v) and audio. I bet a similar feature is available for the 396. Additionally, some cables are available that have the data cables in them so you can actually interface it to your encoder for pressure altitude if my memory is correct. I think I read somewhere that you can even link the data cable to an autopilot, but I may be getting cloudy on this now.
