When I get back home I'll post a picture of the VIU / cellular units that I pulled from the trunk of my DTS. If they are the same, it should definitely work.

My unit uses the buttons and microphone to control the motorola module which in conjunction with your cell phone, effectively replaces the cars cell unit.

Basically, it converts the mirror signals and microphone levels into something that is compatible with the bluetooth module which then communnicates to your cell, which actually does the dialing. Unlike the onstar system, you get to use your cell number, minutes and service provider, whomever, whatever that might be.

And hyperboimmv, I dont know if it is patentable, but I'm glad to here that you think it's worthwhile. I love having it in my car, and I thought other caddy folks would love it too, but aside from you, stujak, and cadiallcsts2003, nobody seems interested.

If it looks like it will work , I will hook you guys up with a free unit (less moto kit) to be field tested. I have a few prototypes left over that I can piece together. I only ask that you guys work with me in case there are any bugs. And if it works for you, you can help me spread the word.
