Dejavuuu,
You are correct about the factory vs the after-purchase Uconnect. The factory unit is made by Johnson Controls and the after-purchase one is made by another manufacturer, can't remember who. There was something about patent issues so they had to use two different setups. Not entirely sure about my last comment there.
The factory one uses the built in car stereo speakers and has a mike in the mirror w/ some control buttons to control the Uconnect funtionality.
I don't have this in my Durango, but my research and quest for piecing together a true factory Uconnect has lead me to the above info.
There seems to be 3 basic components to the factory Uconnect:
1) Uconnect mirror w/ mike and controls
2) harness that connects mirror to factory radio and Handsfree control module
3) Handsfree control module located inside the passenger side dash panel which is flush with the door when the door is close. When you open the passenger side door and then look at the side dash panel that was covered up by the door, that's the piece you have to remove to gain access to a little compartment which supposedly houses the Handsfree module. Part of the cover is underneath the rubber door seal IIRC.
The factory schematics indicate that the wiring harness that supports the Uconnect is built into all the Durangos. Guess what? Not true. I took my right side dash panel off and looked for the harness connection and it was not there.
Further verification of the missing connections/harness was when I disconnected the wiring harness to my factory radio. If the Uconnect harness existed from the factory, several pins should have occupied the Molex connector which, in my case, was totally empty. No wires for the Uconnect system existed in the Molex connector, although it could be added later if I had to build a special harness from scratch if I got the connectors to the Uconnect mirror and the Uconnect handsfree module from a doner vehicle.
Anyway that's where I'm at with that project. Now I'm just waiting for a salvage vehicle to pop up somewhere that has this apparently rare option in the Durango to donate those parts for me to use.
Any body else have similar experiences?
Thanks,
Willy
